Bug 316191

Application: ktp-log-viewer (0.5.3)
KDE Platform Version: 4.10.00
Qt Version: 4.8.4
Operating System: Linux 3.8.0-9-generic x86_64
Distribution: Ubuntu Raring Ringtail (development branch)

-- Information about the crash:
- What I was doing when the application crashed:

In the log viewer selected a log and then tried to click on a date to view the log. No Log is displayed, but crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE IM Log Viewer (ktp-log-viewer), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
