Application that crashed: kile
Version of the application: 2.0.83
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-15-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I was working in Kile, typing text (no special characters) and/or moving the mouse, and it suddenly crashes...

It was at 01:30 so it might be related to autosave (which is configured to trigger every 30 mins). I can really not imagine what other uncommon thing I might have been doing.

Strange though, since compiling etc. works fine, so the file system is not damaged.
