Bug 280510

Application: kate (3.4.5)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-33-generic-pae i686
Distribution: Ubuntu 10.04.3 LTS

-- Information about the crash:
Unless I open it from the command line and give it a path to a file, everytime i open it, it attempts to open with 2 files that no longer exist and will become 100% non-responsive till the error message which won't close for 5 minutes or so and once it does it will crash shortly afterwards every time.. Even opening it by calling a file out and attempting to force a new session it will work for a bit, it doesnt become non-responsive but it will still crash after no more than ten minutes regardless if I am doing something or doing nothing.

The crash can be reproduced every time.

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