Application: konqueror (4.11.4)
KDE Platform Version: 4.11.4
Qt Version: 4.8.5
Operating System: Linux 3.12.6-300.fc20.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
I know this is bad but I select-deselect-select page text when reading. Not doing more Konqueror crashed.
A single page was loaded (cplusplus.com/...) and Konqueror was just started a few seconds ago. The bug is reproducible anytime on my system.

The crash can be reproduced every time.

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