Bug 262653

Application: kate (3.5.4)
KDE Platform Version: 4.5.4 (KDE 4.5.4) (Compiled from sources)
Qt Version: 4.6.3
Operating System: Linux 2.6.36-gentoo-r6 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
I wanted to check a long config file, tried to scroll down and Kate crashed.
Why is there still no auto-backup feature for unsaved documents? I lost data multiple times :(

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