Tmda-filter crashes under Python 2.5

[Mibsy]

Running tmda-filter from .forward files under Ubuntu 7.10. Tmda-filter fails as described below when filtering any email message when python is linked to python2.5. It works fine when python is running under python2.4. I also tried installing the tmda software obtained from tmda.net using the source with the same results. Here is the error message from the bounced message. The syslog message is truncated so this one is more informative:

It could be a bug in python2.5 or tmda code that needs adjusted to conform with python2.5... Unfortunately, I'm not really sure.

In further testing, I set up tmda-ofmipd to receive outgoing mail. It calls tmda-inject, which also fails when using python 2.5. I changed the first line in tmda-inject from /usr/bin/python to /usr/bin/python2.4 and it runs fine. Seems like tmda is not python 2.5 friendly.

The Ubuntu version is 7.10, and the uname -a returns... 2.6.22-14-server #1 SMP Sun Oct 14 22:09:15 GMT 2007 x86_64 GNU/Linux

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage . I have classified this bug as a bug in tmda.

Gutsy will reach EOL very soon, there is no room to fix this in time.
