This bug caused or revealed by http://trac.webkit.org/changeset/101201 After this commit, too many tests crash and run-webkit-tests exits early. It means that the test coverage is 0% on Qt WK2 platform, so it is P1-blocker bug. http://build.webkit.sed.hu/results/x86-32%20Linux%20Qt%20Release%20WebKit2/r101201%20%2815922%29/results.html
Maybe it is general WK2 bug, but I can't check it, because Mac-WK2 testers are broken long long time ago.
