Bug 237391

Application that crashed: kate
Version of the application: 3.3.4
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-3-686 i686
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
kate crashes when opening a file. only active session of kate dies, the other one stays active.
the crash is reproducible after it happens for the first time. it constantly occurs when opening files in a defined order.
if i close all kate sessions and then open them again, i can't reproduce the crash.

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