This seems to be a bug in basesink/audiobasesink then. The GAP event
should've had a duration, and the sink should just preroll again
immediately if it's still in the duration. After the duration the
demuxer would have to send a new GAP event.

Can you file a bug about this with a testcase to reproduce it at
http://bugzilla.gnome.org ?
