Application: umbrello (2.7.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Attempting to import a full java project (Java 5) that uses most features of the language and is a medium sized project (1352 classes) and references to many external libraries.

This program seems to crash when importing class by class from the same project. but is ok with importing 'toy' sized projects (5000 LOC , 10~ classes)

- Custom settings of the application:

None, This is a completely fresh install.

The crash can be reproduced every time.

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