Bug 282141

Application: kdevelop (4.2.2)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 2.6.38.8-desktop-4.mga x86_64
Distribution: "Mageia 1"

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

just typing code, didn't see if autocompletion was trying to show something.
don't know if it is related, but I just created a branch in git before editing this file.

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