Public bug reported:

current build number: 146
device name: m75
channel: ubuntu-touch/vivid-proposed
last update: 2015-03-24 13:57:03
version version: 146

After libc 2.21 landed, pulsesink fails constantly when pausing or
seeking the active pipeline.

Abort message:
Assertion 'pthread_mutex_unlock(&m->mutex) == 0' failed at pulsecore/mutex-posix.c:118, function pa_mutex_unlock(). Aborting.

This is basically happens when it tries to unlock a mutex that is
already unlocked.

This issue doesn't happen with libc 2.19.

To reproduce the issue:
GST_DEBUG=*pulse*:5 gst-launch-1.0 playbin uri=file:///tmp/foobar.mp3

Then when playing, just hit control+c, which will then pause the
pipeline, causing the crash. The crash happens with most of the times
you pause or seek the pipeline.
