The bug is causes by the fact that a resize of an empty page causes a layout, thus deleting the qgraphicswebview before setHtml is called, which then deletes it again, causing a double free. Patch coming.

This false rejection is caused by bug 38998. This won't work in the commit-queue until that's fixed, sorry. :(
