nsTraceRefcntImpl::DumpStatistics: 1180 entries

Since no particular classes were displayed, my best guess is that this is a bug in test automation or bloat test code. Is it possible that something overflowed?
See also bug 482236, bug 483500.  This should probably depend on the latter.
The underlying "leak" is the one already tracked in comment 1 bugs.

The new failure message confirms that bug 482236 fix works :-)

The filtering out of the nsRect line is an erroneous side-effect of bug 469509 fix :-(
(See the discussion there about all the good I think of the patch which was checked in...)

I just landed bug 483500, so if this happens again on mozilla-central, we need a new theory about why it's happening.

If it doesn't happen again on mozilla-central, we should probably land bug 483500 on mozilla-1.9.1.

It does still appear on 1.9.1:

OS X 10.5.2 mozilla-1.9.1 unit test on 2009/04/16 13:45:04
bug 483500 is now landed on 1.9.1.

I'm going to allege that it fixed this.  If not, please reopen.
