Bug 241134

Application that crashed: kate
Version of the application: 3.3.5
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.6.2
Operating System: Linux 2.6.31-gentoo-r10 x86_64

What I was doing when the application crashed:
Kate is crashing every hour or so while I am working on several files.  Sometimes the crash happens when I'm saving the file, sometime when I've changed the file from outside of Kate.  I haven't narrowed down reproducable steps to make it always crash.

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