------- Comment #2 from Thomas Vander Stichele  2009-04-11 07:51 UTC -------
After some probing, it seems it happens when I have a queue in my pipeline.

Attaching an example program; run it like this:

GST_DEBUG=*:2 python flacseek.py
/home/thomas/gst/media/small/dark.441-16-s.flac 


and it will show this:

loop 0
loop 1
loop 2

Removing the queue from the example makes it not give STREAM_DECODER_ABORTED
(although it will hang at some point, indicating other races)
