Application: kdevelop (4.2.2)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-13-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
I was restructuring some of my code. So basically i used the ability to find existing references to a functions and clicked through some of them.

- Unusual behavior I noticed:
I'm working on a project based on Rose Compiler (http://rosecompiler.org/ROSE_HTML_Reference/index.html) - it has some large code base, so kdevelop always had some problems with the background parsing and often complains about mission functions or symbols from this library even though they are provided somewhere in the includes.

It's not the first crash i had, but the pattern is not really predictable and often the same task which crashed before works after a restart of kdevelop.
However, most times i notice a rapid decrease on performence before the crash appears.

The crash can be reproduced some of the time.
