Hi Constantin

I think we found that bug last week and were working towards fixing it.

See 
http://qt.gitorious.org/qt/staging/commit/fd043eb78212de5935bc101624818070e1b4fb1b

the commented lines 2361 and 2362. QNetworkAccessManager is sending an invalid 
"Host:" header, which is what causes the 400 Bad Request reply.
