fast/dom/htmlcollection-zombies.html introduced in http://trac.webkit.org/changeset/103873 ( http://webkit.org/b/75410 ), but unfortunately it fails on 64 bit release on GTK and on Qt. (But it passes on 32 bit release and on 64 bit debug)
Skipped on Qt and on GTK http://trac.webkit.org/changeset/103899
I think it might be a security bug, because the original bug report is security bug and the new test introduced in it still fails on GTK and on Qt.
(In reply to comment #2) > I think it might be a security bug, because the original bug report is security bug and the new test introduced in it still fails on GTK and on Qt. It's not a security bug, it's just an unreliable test. I am going to remove this test in bug 75437.
This test was removed by http://trac.webkit.org/changeset/104383, so I have removed it from Skipped lists too: http://trac.webkit.org/changeset/104561
