Application: umbrello (2.8.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-30-generic-pae i686
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Trying to export Entity Relationship diagram as image. The Entity Relationship diagram does not open after Umbrello restart. That is also a bug I found.

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