-- Information about the crash:
- What I was doing when the application crashed:
Simple typing. I had opened 4 C++ projects and the IDE crashed permanently during typing. Sometimes it crashed when starting the compiler. Ther are no special plugins installed. I use git as repository

The crash can be reproduced every time.

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