Ok, I know the problem.

setFixedLayoutSize is called with a different value than the default because
WebCore::IntSize's default constructed value is valid: 0x0.  Qt's QSize default
constructed value is invalid: -1x-1.  Thus, a mismatch occurs and it
setFixedLayoutSize tries to do a layout.

This only happens with Qt port because other ports use IntSize(0x0) which is
the same default constructed.

However, it is important to note that if Frame::createView(...) was called with
different values than the default ScrollView constructed values for
scrollbarModes for instance, this same crash would happen.

I'm producing a patch for the QSize/IntSize problem, but the larger issue
should still be fixed.
