Description of problem:
From time to time Pidgin freezes and eats 100% of cpu. After some time in this 
state it comes back to normal state and I can see that my Jabber server was 
disconnected. My jabber server usually has problems with stability, so I thing 
this could be caused by server crash or by network issues.


Version-Release number of selected component (if applicable):
pidgin-2.3.1-1.fc8.x86_64


How reproducible:
from time to time


Steps to Reproduce:
1. watch Pidgin with a Jabber account


Actual results:
window freezes, 100% CPU usage


Expected results:
no freeze, no big CPU usage


Additional info:
$ gdb attach 3046
