Version:           0.50.50 (using 4.00.68 (KDE 4.0.68 >= 20080402), compiled sources)
Compiler:          gcc
OS:                Linux (i686) release 2.6.24-15-generic

Kdenetwork rev. 794586

Testcase is simple :) :
1/ Fire up kopete,
2/ Open a chat window (tested with a MSN contact)
3/ Close the chat window
4/ Crash.

If Behavior/Chat/"Always show tabs" is unchecked, kopete won't crash.


Trace :
