pymsnt 0.11.3-5 fails to start due to broken python-twisted-words 10.2.0-1 (AttributeError: 'module' object has no attribute '_parse')

[Lars T. Mikkelsen]

After upgrading to natty, pymsnt 0.11.3-5 now crashes at startup with the following traceback:

Traceback (most recent call last):
  File "/usr/share/pymsnt/PyMSNt.py", line 14, in <module>

  File "/usr/share/pymsnt/src/main.py", line 390, in main

This is a regression in Twisted 10.2.0 as described in the following ticket:
http://twistedmatrix.com/trac/ticket/4771

The issue was fixed for Twisted 11.0.0:
http://twistedmatrix.com/trac/changeset/30430

Applying the change locally against 10.2.0 resolved the issue for me.

This also affects pyaimt 0.8.01-2

the twisted-words package was built with quilt so it was pretty easy to put the patch to fix this problem into the ubuntu package. The problem isn't likely to impact debian as they skipped the 10.2 version of twisted-words and went to 11.0 which has the fix applied.

I uploaded a modified version of the package to my own ppa https://launchpad.net/~diane-trout/+archive/nmu

The patch against the ubuntu package appears to be available at:
https://launchpadlibrarian.net/73753572/twisted-words_10.2.0-1_10.2.0-1ppa1.diff.gz

Though I tested building my own binary version of the debian package, and didn't test the source archive I uploaded. (Though both were built from the same extracted debian source package.

pyicqt is also affected:

@Diane Trout:

thanks, with you're updated package, it works!

[Diane Trout (diane-trout)]

@abma

You're welcome, I'm glad the updated package helped.

It would be very helpful if some enterprising individual would help us (Twisted) do a 10.2.1 maintenance release with this patch. See http://twistedmatrix.com/trac/ticket/4798 and http://twistedmatrix.com/trac/ticket/4799

[Diane Trout (diane-trout)]

What help do you need?

I looked through your svn repository at http://twistedmatrix.com/trac/browser/trunk and didn't see a release-0_10_2_1 tag yet.

[Diane Trout (diane-trout)]

Ok I have a branch in launchpad to try and put together the patches listed above. The twisted svn server was down for much of today so I didn't manage to make much progress.

The branch is at:
https://code.launchpad.net/~diane-trout/twisted/prepare-10.2.1

And I've only merged one of the patches in and verified that the number of successful test cases incremented by 2.

Status changed to 'Confirmed' because the bug affects multiple users.
