Application: umbrello (2.5.5)
KDE Platform Version: 4.5.5 (KDE 4.5.5)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic-pae i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Imported a package of java classes into the application and then i clicked (double possibly?) the lower left hand side where it showed a TON of "things/options" that I wasn't sure what they were (this is my first time using this UML software, not first UML software). So I clicked on something in that list, to see what it was, and what options it gave me. (I was just exploring the application)

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