Bug 283891

Application: konversation (1.3.1)
KDE Platform Version: 4.7.1 (4.7.1)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- Unusual behavior I noticed:

Desktop screen flashed however KDE continued to run flawlessly (Running dual monitor config 1280x2048), konversation is the only affected program.

The crash can be reproduced every time.

-- Backtrace:
Application: Konversation (konversation), signal: Segmentation fault
