Application: kdevelop (4.3.1)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
After the upgrade to either precise or KDE 4.8.3 my syntax highlighting for keywords in neither C nor c++ words correctly, they dont get bold, even the settings are correct .. so i reinstalled kdesdk, katepart, kate, kwrite and so on ... and now kdevelop doesnt work anymore
- Unusual behavior I noticed:
syntax highlighting doesnt work correctly

The crash can be reproduced some of the time.

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