-- Information about the crash:
I can not recreate this problem consistently (or at least on purpose) but at least twice in one night I was undo-ing changes I had made to a tex file and Kile crashed with the attached backtrace.

The crash does not seem to be reproducible.

 -- Backtrace:
Application: Kile (kile), signal: Segmentation fault
