I think it is likely to be in QtWebKit2.3, the loop looks like it is happening 
in qt_runtime_qt4.cpp, which have had some of the most tricky merges. It is 
entirely likely one of the merges made a mess of one of the many special 
cases. Then again, it could be the same problem is in trunk. 

I would suggest you open a bug on webkit, and if you could step through the 
loop it and identify why and where it happens, it might give us a better idea 
of what is wrong.
