Your guess is as good as mine - could be intermittent and related to bug 575294, intermittent and unrelated, or it could be permaorange on Win PGO only and I just don't know it yet. https://tbpl.mozilla.org/php/getParsedLog.php?id=12148097&tree=Mozilla-Inbound Rev3 WINNT 6.1 mozilla-inbound pgo test mochitest-other on 2012-05-28 20:52:56 PDT for push 6d605438199c slave: talos-r3-w7-074 16258 INFO TEST-START | chrome://mochitests/content/chrome/toolkit/content/tests/chrome/test_hiddenitems.xul 16259 ERROR TEST-UNEXPECTED-FAIL | chrome://mochitests/content/chrome/toolkit/content/tests/chrome/test_hiddenitems.xul | blur 10,slider - got [object XULElement], expected [object HTMLInputElement]
Intermittent, but extremely frequent, apparently.
Okay, that's scary - it wasn't intermittent, it was permanent, but it wasn't counted as a failure, so unless something else in the run failed, it showed as green - https://tbpl.mozilla.org/php/getParsedLog.php?id=12145939&tree=Mozilla-Inbound is the log for one of the "green" runs on your push. Backed out, but, how did that not count as a failure?
Summary: Intermittent test_hiddenitems.xul | blur 10,slider - got [object XULElement], expected [object HTMLInputElement] → Permanent, but intermittent counted as failure test_hiddenitems.xul | blur 10,slider - got [object XULElement], expected [object HTMLInputElement]
One possible explanation - bug 678420 was a test that failed, then navigated back in history, loading the previous test into the current test's context, hiding its failures.
There's a bug in the preceding test, test_focus_anons.xul - it doesn't remove its blur event listener at the end of the test, so it depends on the bug that part 1 in bug 575294 fixes. https://tbpl.mozilla.org/?usebuildbot=1&tree=Try&rev=2f33cd615bac

BTW, backing out was the right call. It's really scary that we can have failures like this and still report the test run as succeeding. Do you know if we have a bug open on this?

Yeah, bug 677964, though so far nobody seems to have had any ideas about it.
