[Csaba Osztrogonác]

They aren't fails, they are crashes. :-/ We shouldn't paper over serious crashes with skipping tests.

[Csaba Osztrogonác]

Skipping didn't help us, because now the following tests crash:

fast/frames/frame-deep-nested-resize.html
fast/loader/stateobjects/pushstate-in-data-url-denied.html

[Csaba Osztrogonác]

I tried reverting r96070 locally, and all tests pass for me.

96070 is hurting our QtWK2 tests also: https://bugs.webkit.org/show_bug.cgi?id=68873

[Csaba Osztrogonác]

It isn't Qt specific bug, because all tests crash on Snow Leopard WK2 bot too.
