See http://test-results.appspot.com/dashboards/flakiness_dashboard.html#showExpectations=true&tests=media%2Ftrack%2Ftrack-delete-during-setup.html

Here's the stack trace:

Previously it was hitting an ASSERT(inDocument()), but that was removed in http://trac.webkit.org/changeset/111941.  Note that these tests are skipped on, at least, WebKit/Mac.  Here's the entry, I wonder if it's out of date:

# The mac port has no support for <track>
# https://bugs.webkit.org/show_bug.cgi?id=43668

I'm going to skip this test on GTK as well until the fix for this crasher lands.
