-- Information about the crash:
Kate had been running for a few days stably prior to the crash. I just made a new file and was editing it. I went to delete some text at the end of the file (can't remember whether it was highlighted, or just backspacing) and Kate died as soon as I hit backspace.

Xubuntu 10.04, Xubuntu session

File system browser
