After installing XML-RPC revision 2624 Trac fails with "ImportError: No module named posixpath"

[J.Kraaijeveld@…]

After installing XML-RPC revision 2624 Trac fails with "ImportError: No module named posixpath" when accessing the Trac for the first time. The module mentioned is available in my Python environment (/usr/lib/python2.4/posixpath.py).

This is also reported in the Trac ticket system: ​http://trac.edgewall.org/ticket/4280. The fixes that are mentioned (moving the import etc) lead to crashing later in the session. I report this bug here also as it appears to occur only in the XML-RPC plugin and not in any other plugins that use the same import (e.g. iniadmin).

The error I am getting:

Traceback (most recent call last):

Somebody else pointed out to me that I was using the wrong XML-RPC branch (0.10 instead of trunk). If I use the trunk branch, it works. Still strange though: the old plugin may exibit bugs but this does not look like that kind of bug.

Sorry for the inconvenience.

This looks similar to #1536 and possibly #164.

I have a suspicion that this is due to some freakiness going on in the pydoc module, so I've removed all reference to it.
