-- Information about the crash:
- What I was doing when the application crashed:
The first time I try to edit a file the program crashes. I have had this problem

Comment 1 Milian Wolff 2010-12-26 15:02:36 UTC 
I'd say you should double-check no BIC changes occurred triggering this really strange crash. ~ITextAssistant is empty for me.

Anyhow, if rebuilding kdev* does not hep, run it through valgrind and show us the log:

valgrind --track-origins=yes --num-callers=25 kdevelop

bye
