           Summary: interleave doesn't close properly
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad

     GNOME version: 2.21/2.22
   GNOME milestone: Unspecified


Please describe the problem:
I have a pipeline with multichannel audio (6 or 8, both give the same result)
being interleaved. From the command line, when I try to exit with ctrl-C, the
program doesn't exit until I hit control-c again and also produces a low
frequency sawtooth like sound until I exit. In a C program, when the pipeline
should be destroyed it also hangs (my guess is some of the threads don't exit
properly).Note that the same example in mono or 2 channel audio does NOT hang.

Steps to reproduce:
gst-launch-0.10 -v interleave name=i ! audioconvert ! queue ! jackaudiosink
sync=false \
 audiotestsrc volume=0.5 freq=200 is-live=true ! audioconvert ! queue ! i. \
 audiotestsrc volume=0.1 freq=300 is-live=true ! audioconvert ! queue ! i. \
 audiotestsrc volume=0.1 freq=500 is-live=true ! audioconvert ! queue ! i. \
 audiotestsrc volume=0.1 freq=700 is-live=true ! audioconvert ! queue ! i. \
 audiotestsrc volume=0.1 freq=900 is-live=true ! audioconvert ! queue ! i. \
 audiotestsrc volume=0.4 freq=1100 is-live=true ! audioconvert ! queue ! i. \
 audiotestsrc volume=0.4 freq=1300 is-live=true ! audioconvert ! queue ! i. \
 audiotestsrc volume=0.4 freq=1400 is-live=true ! audioconvert ! queue ! i. \


Then try to exit with control-C.

Actual results:
It will hang as described with this message:

Caught interrupt -- handling interrupt.
Interrupt: Stopping pipeline ...
Execution ended after 894420256 ns.
Setting pipeline to PAUSED ...
Setting pipeline to READY ...
/pipeline0/jackaudiosink0.sink: caps = NULL
/pipeline0/queue0.src: caps = NULL
/pipeline0/queue0.sink: caps = NULL
/pipeline0/audioconvert0.src: caps = NULL
/pipeline0/audioconvert0.sink: caps = NULL

until control-C is used again.

Expected results:
The program should exit normally and the audio should be killed.

Does this happen every time?
80% of the time (sometimes it does quit normally).
