Original commit message from CVS:
Patch by: Sjoerd Simons <sjoerd at luon dot net>
* plugins/elements/gstqueue.c: (gst_queue_chain):
Recheck queue filledness after signalling the overrun when we're about
to leak downstream because we released the lock when emitting the signal
and the queue could be empty again. Fixes #352345.
