Possible revisions causing this: <a href="http://trac.webkit.org/log/?rev=192721&amp;stop_rev=192720&amp;verbose=on">http://trac.webkit.org/log/?rev=192721&amp;stop_rev=192720&amp;verbose=on</a>
My guess is that this was caused by <a href="http://trac.webkit.org/changeset/192721">http://trac.webkit.org/changeset/192721</a> but I didn't tested it.

This regression don't seems to happen on Linux ports (only Mac ones).</pre>
