Application: umbrello (2.6.2)
KDE Platform Version: 4.6.2 (4.6.2) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic i686
Distribution: Ubuntu Natty (development branch)

-- Information about the crash:
I've just tried to import all java from a java project, so Umbrello closed. Later, I tried with a module of my java project and the same behaviour occurred.

The crash can be reproduced every time.

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