Application: umbrello (2.7.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: I had added an attribute to a class but was having problems with my wireless keyboard so I tried deleting it manually using the mouse.  The item highlighted, then changed to wait for me to rename it, but I deleted it before I did.  Then the program crashed.

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