Application: kdevelop (4.0.1 (using KDevPlatform 1.0.1))
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-24-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

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

KDevelop crashed whilst scrolling in a file, so I re-opened it. I then re-opened Kdevelop (set to reload the last open project), and attempted to scroll in another file. It crashed again.

The crash can be reproduced some of the time.

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