Bug 333443

Application: konqueror (4.8.5 (4.8.5))
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-23-generic-pae i686
Distribution: Ubuntu 12.04.4 LTS

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

- Custom settings of the application: konqueror  was displaying duckduckgo.com   and I pasted into it from LibreOfficeWriter to the search field of duckduckgo.com. I pasted 'Lunar eclips' into search field of duckduckgo.com. Konqueror crashed.

The crash can be reproduced some of the time.

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