           Summary: capsfilter: assertion `caps != NULL' failed
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: Normal
         Component: gstreamer (core)
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: sebas642 at yahoo.ca

Run the following pipeline:
   gst-launch-0.9 fakesrc num-buffers=1 ! video/x-raw-yuv ! fakesink
   
      (gst-launch-0.9:18474): GStreamer-CRITICAL **: gst_caps_ref: assertion
`caps != NULL' failed
      (gst-launch-0.9:18474): GStreamer-CRITICAL **: gst_caps_unref: assertion
`caps != NULL' failed

The assertions are triggered by the GstBaseTransform class (from which
capsfilter inherits) which refs and unrefs the caps from the source pad in
gst_base_transform_prepare_output_buf(). These caps are not set until the first
buffer has passed through.
