Application: kate (3.5.3)
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-23-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
Had finished running a couple of compiles in the terminal window to generate compiler errors to post for a class assignment. Clicked the 'x' to close Kate and Kate crashed.
I do have a question, why crashes by kate are being reclassed as a duplicate of a Yakuake bug?
I do run Yakuake but it is not crashing. It continues to function just fine after Kate goes down.
Any explanation would be appreciated. This bug if it continues is going to make it very difficult to continue using Kate. Can't afford to keep losing school work to crashes.

The crash can be reproduced some of the time.
