Application: umbrello (2.7.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-26-generic x86_64
Distribution: Linux Mint 12 Lisa

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

Selected Java as the language of choice, then selected Import Project from menu.  Browsed to main source folder containing Java source files.  Upon selecting, the application flickered and briefly displayed a changing set of classes in the left-hand tree view, then suddenly crashed mid-way through the process.

The crash can be reproduced every time.

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