Bug 306760

Application: umbrello (2.8.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-23-generic i686
Distribution: Linux Mint 13 Maya

-- Information about the crash:
- What I was doing when the application crashed:
I was attempting to set sequence numbers in a sequence diagram.  I was attempting to set the third to 3, and typed '3' twice before realizing the dialog didn't have focus.  When I moved the mouse to give it focus, umbrello crashed.

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