Bug 262025

Application: kate (3.5.90)
KDE Platform Version: 4.5.90 (4.6 RC1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Closing a cmakelists.txt file with a vertical split between two code files.

- Unusual behavior I noticed:
The cmakelists.txt file was reaching the end of file half way down the scroll bar and would loop back to the top when the bottom was reached of the file, not the scroll bar.

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