I have pidgin 1:2.5.5-1ubuntu7 installed and I still see a SIGILL crash. Backtrace follows (with some of my personal information obscured):

You can ignore my comment with the backtrace, it's probably a libxml2 bug (not the original MSN thing).

[Ricardo Pérez López (ricardo)]

@Shaw:

Seems to be the same bug as mine. I opened a bug #358516 about it. Do you use Jabber accounts?

[Shaw Terwilliger (sterwill)]

Yes, I use Jabber via Google (both gmail account and paid apps account).
