Application: kword (2.2 RC 1)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I was creating an outline for a paper, and thought to play with the styles to see if I can create something easier to work with it. I end up deleting the style (without ever using it) and KWord crashed. I clicked restart on the crash reporting tool, and KWord tried to recover my work, but failed. I do not recall what KWord said in that error.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: KWord (kdeinit4), signal: Segmentation fault
