Ok, just tried to reproduce it, and it's not about scrolling virtual desktops, but scrolling with mouse wheel over this page opened in akregator: http://izismile.com/2012/11/26/10_more_funny_bets_that_youll_always_win.html . It's crashing every time when I'm trying to scroll page down with mouse wheel.

Webkit crash. Also crashes in rekonq.

Please report this issue to the webkit bug tracker. See http://trac.webkit.org/wiki/QtWebKitBugs for the details.
