Change milestone name gives an internal server error

Getting internal server error when changing milestone name.

To get this error, on the admin panel I change the milestone name, and then I have the following error:

Another weird thing is that after the error, part of the tickets have its milestone changed to the new milestone name, which is not visible on the Manage Milestones administration screen, that is, it looks like the milestone is not created, and the other part continues with the previous milestone name. This last milestone continue existing on Manage Milestones administration screen.

Another hint for this issue. I did a batch update, setting "add hours to ticket" to all tickets on my db and this error stopped appearing. I wonder if it was my fault during configuration. Doing something likean upgrade or so.

Sorry, I guess I never saw this. I can see where there might be a null error there. I can probably be defensive and resolve the error without having to actually recreate it.

I think I found and fixed this error in another ticket #13219 Try version 1.5.0(b)

Thanks for the bug report and cheers, Russ Tyndall
