Bug 284390

Application: kate (3.7.2)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
* Open a file with right-click "Open with Kate"
* (close "tip of the day")
* either click on the icon or File/Open... to open another file
* choose a file to open

Kate crashes

The crash can be reproduced every time.
