Application: kate (3.4.1)
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-17-generic x86_64
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
I have a kate session with about 10 local files and i wanted to close them using the close keyboard shortcut (Ctrl+W on my system). After closing a few files (about 3 or 4) kate crashes. 
When i restart kate and try again, i have the same crash again.

The crash can be reproduced every time.

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