Bug 330225

Application: konqueror (4.11.5)
KDE Platform Version: 4.11.5
Qt Version: 4.8.5
Operating System: Linux 3.12.6-300.fc20.i686+PAE i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed: I was simply looking at a Web page. The cursor may have been above a hyperlink, but I did not click on it. I was quite surprised by the Konqueror crash. It was quite unexpected.

-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".
