Application: kdevelop (4.0.2 (using KDevPlatform 1.0.2))
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Simply opening and closing KDevelop will cause a segmentation fault on close.  However, no data is corrupted and the system works perfectly fine.  Altering settings and then closing the application saves those settings properly, so there is little to complain about :-).

This is a fresh Ubuntu 10.10 Desktop install.

The crash can be reproduced every time.

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