Bug 278126

Application: choqok (1.0)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed: Clicking a username in messages, then clicking "show messages from this user" causes Choqok to segfault, when it is expected to open a "search" tab with given user's messages.

The crash can be reproduced every time.

-- Backtrace:
Application: Choqok (choqok), signal: Segmentation fault
