Pasted an email body which resulted in a ticket that was not viewable

I pasted an email (from MS Outlook) as a new comment on an existing ticket, I didn't press preview and went straight to Submit Change. The result was the error below whenever I attempted to view the ticket:

Oops…
Trac detected an internal error:

If you think this really should work and you can reproduce it, you should consider reporting this problem to the Trac team.

Go to http://trac.edgewall.org/ and create a new ticket where you describe the problem, how to reproduce it. Don't forget to include the Python traceback found below.

Collecting Shell Commands (Non-Code Specific) 




NOTE: THESE COMMANDS NEED TO BE RUN ON BOTH CONTROLLERS AND OUTPUT SAVED IN SEPARATE FILES 
Please send files to dasdsupt@us.ibm.com

ITEMS NEEDED: 
1-Null-Modem Cable (This is a Serial Crossover Cable) 
2-Server, workstation, or laptop installed with Windows 95, 98, 2000, 

How to connect to the FAStT and capture output using PuTTY from Windows:

1) Launch PuTTY.exe
2) Type in the Controller IP address
3) Select the "Rlogin" protocol
4) Under Category: click "Logging"
5) Select "Log all session output"
6) Click the "Browse" button and navigate to a directory where you can e-mail from
7) Type the file name to include the controller you are connecting to. 
i.e. ctrl_A_shell_output.log
8) Click Save
9) Click Open

---------------------------------------------------------------------------------
How to connect to the FAStT and capture output using HyperTerminal:

Hyper Terminal Session Parameters:

1-COM Port = COM1
2-Baud Rate = 9600 or higher
3-Data Bits = 8
4-Stop Bits = 1
5-Parity = None
6-Flow Control = Xon/Xoff

1) Connect the appropriate serial cable to com port
2) Launch HyperTerminal in W2K it is located at:
-->Start-->Programs-->Accessories-->Communications-->HyperTerminal
3) In the Connection Description type FAStT
4) In the Connect To select the COM port that you are connected to. i.e. COM1
5) COM# Properties should be: 
Speed: 9600 or higher - default is 38400 (if doing firmware load select 115200)
Data bits: 8
Parity: None
Stop bits: 1
Flow control: Xon / Xoff
6) Select Transfer
7) Select Capture Text
8) Click the "Browse" button and navigate to a directory where you can e-mail from
9) Type the file name to include the controller you are connecting to. 
i.e. ctrl_A_shell_output.log
10) Click Save
11) Click Start

Note: HyperTerm will remember the file name of the capture file but will not automatically start capturing, so make sure that you redo steps 6-11 when you connect to the second controller.

---------------------------------------------------------------------------------
How to connect to the FAStT and capture output using RLOGIN on AIX:

1) Logon to the AIX box and get to a command prompt.
2) Issue the following command to start a script log that can later be downloaded and saved: script -a /tmp/fast_shellcmds_ctrlA.txt
3) Type rlogin ##.##.##.## --> where ## is the IP address of controller A
4) Enter password to get into the shell. Default password = infiniti -- older systems password = password
5) Issue all of the PD commands required
6) Type exit (this should take you out of the FAStT shell and back to the AIX console)
7) Type exit (this is to close the script log and save the file)
8) Issue the following command to start a script log that can later be downloaded and saved: script -a /tmp/fast_shellcmds_ctrlB.txt
9) Type rlogin ##.##.##.## --> where ## is the IP address of controller B
10) Enter password to get into the shell. Default password = infiniti -- older systems password = password
11) Issue all of the PD commands required
12) Type exit (this should take you out of the FAStT shell and back to the AIX console)
13) Type exit (this is to close the script log and save the file)


Initial Shell Access Procedure:

1-Press Ctrl+Break 3 time consecutively.

2-When you see "Press Space Bar Within 5 Seconds To Set Baudrate," press the Space Bar. 
Wait till you see that the Baudrate reports being set before going to step 3.

3-Press Ctrl+Break once.

4-When you see "Press Space Bar Within 5 Seconds To Set Baudrate, or Press ESC To Exit To Shell", press ESC.

5-You should see a login prompt. Key in the following password:

For 3526 , 3552 ,1742 ,3542 Fibre Controllers password is = "infiniti"

When a call is sent to next level for support the output of these commands should be run first and checked for failures before sending it up.  If you need assistance with decoding the output please let me know.

The following commands should be run when done collecting shell output:

unld "Debug"
exit



(See attached file: putty.exerename)...........................
Here is the putty program used for rlogin. You need to rename it to putty.exe (if needed)


( If this is for an IBM CE the following list Part numbers of cables)
that may be needed)
Laptop to rack power adapter cable .....45p5834
Ethernet Cross over cable 25' ..................39X8924
10' ..................45P5860
Ethernet Straight Through 10' ..................45P5861
Communication Kit ..................62H4857
1 4 headed data set eliminator cable
1 9 pin serial cable male / female
1 9 pin female gender binder
serial cable for  3542  (FAStT 200)   is p/n19K1179

(In [3716]) Added call to trac.html.escape for text of email in 0.10 version. Closes #2795

[flakrat]

Howdy, I just wanted to confirm that I have tested the latest version of emailprocessormacro and it did resolve the issue.

Thanks for the fix
