-- Information about the crash:
- What I was doing when the application crashed:

I wanted to select text in my PDF preview, so I clicked the "Browse" button to switch to a text-selection tool. I get the same crash behavior when I restart Kile.

The crash can be reproduced every time.

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