Comment 1 Myriam Schweingruber 2011-08-24 00:17:04 UTC 
It is really beyond my understanding why Fedora ships a beta version of Qt 4.8, there seem to be a lot of problems and regressions. Could you maybe test again with the stable Qt 4.7.3?
Comment 2 Myriam Schweingruber 2011-08-24 00:30:02 UTC 
Rex, any idea where that broken Qt comes from? The latest stable is 4.7.3 and there are not even official beta ones of 4.8, AFAIK 4.8 will be skipped
Comment 3 Rex Dieter 2011-08-24 12:51:31 UTC 
Qt 4.8 being skipped is news to me.

What about this?
http://labs.qt.nokia.com/2011/07/19/qt-4-8-beta-released/
and webkit news
http://blog.forwardbias.in/2011/08/on-webkit-and-webkit2.html
which implies qtwebkit-2.2 will be released along with qt 4.8
