[Qt-creator] QtCreator(0.9.2RC1) crash when press F1 to lookup wrong keyword on Mac

[eike.ziller at nokia.com]

Hm, thanks for the details,
looks like there happens something related to webkit/safari plugins.
So it might be easy to reproduce - but perhaps only with specific plugin(s) installed :)
It would be very interesting to know what safari plugins you have installed (Start Safari, Help->Installed Plugins).
At least for the poor QWebKit guys. For Creator we should probably just make sure it doesn't try to load any of these plugins at all (at least till we have movies and flash in the documentation ;) )
