 Hello,

 I'm using pidgin 2.7.0 from PPA on Ubuntu Karmic 9.10. Every time I start
 it, it crashes with SIGSEGV without any action of myself.

 I've added the debug (started pidgin with -d). Hope you find it usefull.
 Apport shows a crash, but I don't attach the log because of the size of 9
 MB (core dump).

 '''gdb-Backtrace:'''
