Patch fixing the bug

If an QVariantMap containing QObjectStar is added to the to QtWebkit
Javascript, it's use causes Segmentation Fault.
It happens because, in the case QMetaType::QVariantMap, the "root" object that
is inside of a PassRefPtr is passed recursively inside a loop to recover the
content of the map, but the PassRefPtr semantics prohibit its use inside a
loop, so the "root" object mus be passed using the method "PassRefPtr::get" in
order to keep the current reference.
