Play a video like this one:

https://www.facebook.com/photo.php?v=10152179935133691

During playback move the position back and forth by clicking quickly on different parts of the progress bar (NOTE: click, don't drag).

Repeat the process a few times, and the web process will crash:

I reproduced this with webkitgtk 2.4.3 using the MiniBrowser. The master branch seems to work fine.

This is a regression introduced by this commit:

http://trac.webkit.org/changeset/160688

It was also fixed in master with the jsCStack branch merge (r163027).
