           Summary: GstGhostPad fails when set to PLAYING for the second
                    time
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gstreamer (core)
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: webmaster at mikeasoft.com

     GNOME version: Unspecified
   GNOME milestone: Unspecified


When using gnonlin to play a file in Jokosher, then stopping the playback and
starting it again the following error is returned:

(Jokosher:17932): GStreamer-CRITICAL **: Padname '':src does not belong to
element gnlsource0 when removing

(Jokosher:17932): GStreamer-CRITICAL **: gst_pad_set_active: assertion
`GST_IS_PAD (pad)' failed

 I've tracked this problem down to revision 1.49 of gstghostpad.c

 To reproduce:

 1. Start Jokosher
 2. Add an instrument
 3. Import a file
 4. Press play
 5. Press stop
 6. Press play

 With a version of GStreamer prior to this commit everything works as expected,
however after 1.49 playback stops and the error is seen. Attached is a
GST_DEBUG=5.
