When I try to run a simple flac player that uses the typefind element and 
threads, it plays for 5 to 15 seconds and then stops.  Sometimes it gives
an error message and other times it consumes 100% cpu and hangs.  I tried
about 8 different flac files ripped from different albums and the problem
occured with all of them.  I am running gstreamer 0.7.6.  The command that
fails is:

gst-launch-0.8 \{ filesrc location=test.flac \} ! \{ queue ! typefind !
flacdec ! audioconvert ! osssink \}
RUNNING pipeline ...
ERROR: from element /pipeline0/thread1/flacdec0: Could not decode stream.
Additional debug info:

Additional debug info:

these commands work fine:
gst-launch-0.8 \{ filesrc location=test.flac \} ! \{ queue ! flacdec !
audioconvert ! osssink \}

gst-launch-0.8 filesrc location=test.flac ! typefind ! flacdec !
audioconvert ! osssink
