pidgin 2.7.1 crashes on Ubuntu 9.10 32bit

[NYU CS]

Dear all:

Pidgin has been very stable in version 2.7.0.  Since 2.7.1, it start to 
crash, randomly, it seems.

here is the backtrace of the crash. Would someone help me on shedding 
some light on what might went wrong?

It seems that I am the only one who suffered from this...

I am not sure how to file a bug intelligently since I couldn't really 
make out what does these backtrace means:

any explaination on the backtrace and what might be the problem would be 
much appreciated.
