Bug 300792

Application: konqueror (4.8.3 (4.8.3))
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.3.0-trunk-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:
I was working in LibreOffice on another desktop and did not touch Konqueror at all. It just crashed for no apparent reason.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Konqueror (kdeinit4), signal: Segmentation fault
