Description unix1 2011-01-14 02:59:04 UTC

Application: kdevelop (4.1.60)
KDE Platform Version: 4.5.95 (4.6 RC2)
Qt Version: 4.7.1
Operating System: Linux 2.6.34.7-0.5-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

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

scrolled to the class method I needed to edit, created a blank line with carriage return, tabbed several times for indentation, entered "if " (with space without quotes), KDevelop suggestions drop-down appeared, 1 second later KDevelop crashed.

The crash can be reproduced every time.

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