Bot says that this started in this range <http://trac.webkit.org/log/?verbose=on&rev=163079&stop_rev=163074>, which probably implicates <http://trac.webkit.org/changeset/163079>.

Note that this test was crashing about a week ago as well, but that was for an entirely different reason.

Sample crash: <http://build.webkit.org/results/Apple%20MountainLion%20Debug%20WK2%20(Tests)/r163080%20(15681)/fast/events/page-visibility-iframe-move-test-crash-log.txt>
