Application: lancelot (1.9.5)
KDE Platform Version: 4.5.95 (4.6 RC2)
Qt Version: 4.7.1
Operating System: Linux 2.6.37-18-desktop x86_64
Distribution: "openSUSE 11.4 Milestone 5 of 6 (x86_64)"

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

Whenever I am browsing my application list in lancelot, enter an application directory, and then either click or use the no-click interface to select a parallel directory, Lancelt crashes.

- Steps to reproduce:

1. Open Lancelot
2. In the application list, open a folder, say "utilities", either using a mouse click or the no-click interface
3. While that folder is still open, open a different folder, say "system", using a mouse click or the no-click interface

That causes a crash.

The crash can be reproduced every time.

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