OK can reproduce. What's happening is like this:

  |           |src  |   |sin1| +----+                    | |
  |           +-----+   +----+ |sin2|   +---------------+| |
  |                 |   |      +----+   +----+          || |
  |                 |   |      |        |sin3|          || |
  |                 |   |      |        +----+          || |
  |                 |   |      |        +---------------+| |

sin1 is the gconfvideosink's ghost pad, targeting sin2, the autovideosink's
ghost pad, and sin2 targets whatever's inside it (sin3). But because these
elements have fakesinks in NULL and then real sinks in READY, and they remove
their ghost pads whenever the inside element changes, sin1 is left pointing at
an old sin2, which was removed when xvimagesink was added to the autovideosink.

Trying to think up a solution, probably involves unsetting the target property
when a ghost pad's internal pad is unlinked. Something like that.
