           Summary: playbin2 crashes when changing volume
    Classification: Desktop
           Product: GStreamer
           Version: 0.10.31
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base
        AssignedTo: gstreamer-bugs at lists.sourceforge.net

Changing the volume in a playbin2 pipeline results in crashes. The elapsed time
until the crash happens is random, usually ranges between seconds and few
minutes.

The attached test code uses pthreads to play an audio file, while changing the
volume randomly. It segfaults after some seconds. Using playin instead of
playbin2 in this code eliminates the crashes.

Tested on the following configuration:
Ubuntu 10.04 64 bits
gstreamer 0.10.31
gstreamer-plugins-base 0.10.31
gstreamer-plugins-good 0.10.26
gstreamer-plugins-bad 0.10.20
gstreamer-plugins-ugly 0.10.16

Informal tests on Windows and OSX through the java bindings of gstreamer seem
to indicate that the bug also affects these other platforms.
