I'm using gst core/plugins/ffmpeg cvs from a week ago and totem 1.1.1

1) open a ogm file in totem (video/audio/subtitle)
2) seek near the end
3) leave it go to eos
4) segfault

This works now... I'll leave it open because I discovered another, possibly much
bigger bug, while debugging this: multiple streams EOS. If we have 2 audio
streams, we disable one of them. On EOS, we don't send EOS to the disabled
stream, so although the stream is finished, the pipeline will continue to
iterate until infinity (and eat 100% CPU while doing so).

Update on the above: the easiest way to solve it is to set muted elements to
PAUSED. Doing that and then seeking leads to races described in #165928/#165929,
so I can't commit that... :-(. this sort of stuff may stay broken until 0.9...

I'm pretty sure this bug is no longer valid in 0.9, the question being whether
we want to keep it open for 0.8... I would say no, because everyone knows
gstthread will never reach Zaroo Boogs. Closing as FIXED, because the original
issue is fixed.
