Here's the test diff. It seems that it's just timing out:
+FAIL: Timed out waiting for notifyDone to be called
Test that QuickTime file with RTSP URL generates a load error.
-EXPECTED (video.error != 'null') OK
-EXPECTED (video.error.code == '4') OK
-EXPECTED (video.networkState == '3') OK
-END OF TEST
It's normal that it fails and that it's skipped for us because we *CAN* play rtsp streams. So no error received in this test => timeout :)
Thanks. I'll update the skipped list explaining why this test is skipped.
