I just hit this assertion (while Safari was in the background. I do not know how to reproduce): ASSERTION FAILED: m_frame->view() == this (WebCore/page/FrameView.cpp:650 void WebCore::FrameView::scheduleRelayout()) I very much suspect it is a result of <http://trac.webkit.org/projects/webkit/changeset/25395>.

The test case does not crash release builds, although I think with more complicated layout it might. This is still a P1 regression in my opinion because of the change of behavior (blur event dispatched where it previously hadn't been, and with arbitrary timing). See also bug 12768.
