Description Martin Klapetek 2010-06-24 14:10:26 UTC
Application: kdevelop (4.0.0 (using KDevPlatform 1.0.0))
KDE Platform Version: 4.4.85 (KDE 4.4.85 (KDE 4.5 Beta2))
Qt Version: 4.7.0
Operating System: Linux 2.6.34-38.fc14.x86_64 x86_64
Distribution: "Fedora release 13 (Goddard)"

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

I expanded the project sidebar, located one file, right clicked, selected Rename, a dialog poped up and immediately after that it crashed. Everytime.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop.bin), signal: Segmentation fault
