Bug 225482

Application that crashed: kate
Version of the application: 3.3.5
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-17-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Several source text files had been opened in kate. After updating the files by an external application (git), kate has correctly reported that the files had been modified (red icon before each file name in the list). After trying to save some of the contents stored in kate (by overwriting the files modified by git), kate crashed.

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