Version details: 13.09.2005 CVS
Distribution/Version: archlinux

1. Create a pipeline that's supposed to play some video 
   (ie. filesrc ! dvdec .video ! fakesink)
2. Set the pipeline to PAUSED
3. Set the pipeline to READY
4. Remove elements from the pipeline and destroy the pipeline
5. Add the elements back to a new pipeline 
   (ie. filesrc ! dvdec. video ! xvimagesink)
6. Set the new pipeline to PAUSED

Fails with: (in case of xvimagesink)
ERROR (0x80c6620 - 0:00:00.106941000)     xvimagesink(29763)

This is valid at least for (dvdec) and (avidemux ! jpegdec) constructions. With
simplier elements (videotestsrc, sinesrc) all works like expected. I'm attaching
a simple test case that triggers the error (C).

For the purpose of the example it's very simple. I bumped on that while trying
to do more complicated things (decodebin based bins added/removed from pipelines)
