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

I have opend Kdevelop4 with PHP Plugin and was beginning to code. After a while ~5Min's it's crashed. Before this crash, kdevelop 4 crashed already. Both times I was pushing and insierting some new Lines. 

Hope this helps?

Version: current SVN/GIT... (what VCS is used..), last compiled today.

KDE 4.5.0

The crash can be reproduced every time.
