KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Opened properties of a class, added one field and one method with one parameter. Application crashed after pressing OK in the window with class properties.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Umbrello UML Modeller (umbrello), signal: Segmentation fault
