Bug 269002

Application: kate (3.6.1)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.37-ck1 x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

I was editing a file in kate when the keyboard input stopped being accepted. Nothing was appearing on screen in kate. Clicking in other windows and typing there still worked fine but I was unable to type any more into kate. Occasionally an 'a' or an 's' would should up but most keyboard input was ignored. Then I figured I had to close it and when I clicked close, it crashed.

-- Backtrace:
Application: Kate (kate), signal: Aborted
