Bug 300196

Application: konqueror (4.7.4 (4.7.4))
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-17-generic i686
Distribution: Ubuntu 11.10

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

I was searching a word in the document (DVI) using ctrl-F. In the same time it was searching, I clicked on the "miniature" on the left in order to change page.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
