#11996: icq/oscar crash on single user

Reporter:  exa    |        Type:  defect

 Hello,

 recently, when one specific user is sending a message to me via ICQ,
 pidgin crashes instantly. I'm not sure why this happens (I guess that I'll
 just clear off my settings and it should disappear), but feel the
 necessity to post a backtrace to possibly find a bug or a problem that
 could also cause other crashes.

 Affected (tested) 2.6.3 to 2.7.0

 backtrace follows (sorry it's not from debug version, i'm gonna try to
 supply that one too):

 {{{

 I'm gonna do some hacking and report if I come across a viable solution.
 If someone could patch/explain this, please do.

 Cheers
