Sentry Crash Report:

Description Rafał Malinowski 2010-08-18 00:31:40 UTC 
Version:           4.5 (using KDE 4.5.0) 
OS:                Linux

Our application, Kadu (www.kadu.net) uses Qt as its toolkit.
It uses QColorDialog which on KDE uses KColorDialog as its implementation/frontend.

Opening this window (from Kadu configuration window, view/colors) works good, but selecting "Named colors" from combobox results in ugly Segfault.

Reproducible: Didn't try

Steps to Reproduce:
1. download kadu from gitorious: http://gitorious.org/kadu/kadu
2. install it
3. run it under KDE 4.5, open configuration window, open "view" section and "color" tabs
4. click on any color button
5. select "Named colors" from color dialog combobox

Actual Results:  
Crash

Expected Results:  
No crash

Some backtrace:

Program received signal SIGSEGV, Segmentation fault.
