Please describe the problem:
When executing sample pipeline from multipartdemux documentation
(http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-good-plugins/html/gst-plugins-good-plugins-multipartdemux.html),
the ximagesink element doesn't display enything.



Steps to reproduce:
1)
Create /tmp/test.multipart file using the following command (sample pipeline
from multipartmux documentation with "num-buffers=500" added):
$ gst-launch videotestsrc num-buffers=500 ! video/x-raw-yuv,
framerate=\(fraction\)5/1 ! jpegenc ! multipartmux ! filesink
location=/tmp/test.multipart

2)
Execute the following command (from multipartdemux documentation):
$ gst-launch filesrc location=/tmp/test.multipart ! multipartdemux ! jpegdec !
video/x-raw-yuv, framerate=\(fraction\)5/1 ! ffmpegcolorspace ! ximagesink

There's no error reported, but the commad doesn't open any window with
ximagesink output.

3)
Execute the same command without setting framerate:
$ gst-launch filesrc location=/tmp/test.multipart ! multipartdemux ! jpegdec !
ffmpegcolorspace ! ximagesink

This time ximagesink works as expected.


Actual results:

Does this happen every time?
