Bug 287042

Application: lancelot (1.9.5)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.1.0-1.2-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Opened Lancelot selected a category. Once I went into a sub category, it crashed. Traversing around categories either backwards or forwards will crash Lancelot. Happens all of the time, it is not useable.

The crash can be reproduced every time.

-- Backtrace:
Application: Lancelot (lancelot), signal: Segmentation fault
