Description Thorsten Staerk 2011-04-09 15:52:59 UTC
Application: ktimetracker (4.7.0)
KDE Platform Version: 4.6.41 (4.7 >= 20110106) (Compiled from sources)
Qt Version: 4.7.1
Operating System: Linux 2.6.37.1-1.2-desktop i686
Distribution: "openSUSE 11.4 (i586)"

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

Start ktimetracker, have at least one task in it. Click "close", then "quit" => ktimetracker crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: KTimeTracker (ktimetracker), signal: Segmentation fault
