Application: ktimetracker (4.11.1)
KDE Platform Version: 4.11.1
Qt Version: 4.8.4
Operating System: Linux 3.8.0-31-generic i686
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
I opened a rather big .ics file (1.3MB) on a fstab-mounted samba share. Several tasks showed those little watches, so I pressed ESC. After about half a minute, ktimetracker crashed.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KDE-Zeiterfassung (ktimetracker), signal: Segmentation fault
