 GStreamer | gst-plugins | Ver: 0.8.x

           Summary: Playbin segfault when switching from READY to PAUSED
                    state
           Product: GStreamer
           Version: 0.8.x
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: critical
          Priority: High
         Component: gst-plugins
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: raphael at slinckx.net
         QAContact: gstreamer-bugs at lists.sourceforge.net
                CC: all-bugs at bugzilla.gnome.org


Steps to reproduce:
1. Modify the media filename in the test case
2. Compile using:
gcc $(pkg-config --libs --cflags gstreamer-0.8 ) gst-test.c -o gst-test
3. Run gst-test

I manage to crash it at attempt 3 most of he time, other people report 10 or 2à
attempts, while thomasvs didn't got any crash.

I think it's a race condition, given these random reproducability problems.

Stack trace:
Program received signal SIGSEGV, Segmentation fault.
