The reason was that the test had a timeout and performing deferred.reject(). We do that a lot in tests "http://mxr.mozilla.org/mozilla-central/search?string=deferred.reject%28%29". The http://mxr.mozilla.org/mozilla-central/source/testing/mochitest/BrowserTestUtils/content/content-task.js#59 is performing `e.toString()` . Can this be changed to not fail?
