This is my first bug report on this bugzilla, I'm not sure what to choose for 'Component' and 'Version' please fix those if needed.
I'm using midori browser and I was able to crash it with one specific webpage (shown in trace), also I was able to crash it with 'midori --plain' which should be simple web browser, no midori code in it, and I don't know if this is a webkit bug, or some other component.

For me, to reproduce this bug it was really simple and always possible (at least for now), when page loads, move up/down (scroll) and it will crash.

webkit packages used 
webkitgtk3-2.2.7-1.fc20.x86_64
webkitgtk-2.2.7-1.fc20.x86_64
I think midori in my case uses webkitgtk (not ...gtk3)
