can also be reproduced with QtTestBrowser 1, load google.hu 2, switch to resizeToContentsMode assert hits 1, load http://www.webkit.org/blog-files/3d-transforms/transform-style.html 2, switch to resizetoContentsMode no assert pages with no composition asserts when setting delegates scrolling on/off.
