-- Information about the crash:
- What I was doing when the application crashed:
I was closing the preview pane in Kile 3 since I use Okular to view my compiled TeX code.  This happens repeatedly.

The crash can be reproduced sometimes.

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