Ignore changing the GConf key to "". Ignore GConf key updates
that don't actually change the string.
For now, ignore the GConf key when the state is > READY, as
it breaks streaming. Sometime it will be nice to bring the
new sink online even mid-stream, by sending NEWSEGMENT info
and possibly prerolling.
