Application: konqueror (4.10.5)
KDE Platform Version: 4.10.5

Operating System: Linux 3.10.4-300.fc19.x86_64 x86_64
Distribution: "Fedora release 19 (Schrödinger’s Cat)"

-- Information about the crash:
Browsing Ebay, checked a box on the left-hand side of the screen to filter the selection of items displayed, crashed. Restarted and checked the same box twice more and it crashed again both times.

Apparently there was something in the program state at that particular moment and it's not an issue with the page itself; a little later I checked the box again and then it worked.

The crash can be reproduced every time.

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