Application: lancelot (1.9.5)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Linux Mint 10 KDE

-- Information about the crash:
- What I was doing when the application crashed: Right-clicking an application entry in order to add it to "favorites".

- Unusual behavior I noticed: After Lancelot menu closed, the popup window "Add to Favorites" stayed on the desktop, and my CPU rose to 100% with Lancelot using 80-90% of it. Lancelot crashed after I hovered over the "stuck" Add to Favorites popup and CPU immediately went back to normal.

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