ximagesrc errors when already played once

[sphaero]

** (pipeviz:26034): WARNING **: 14:40:55.014: ximagesrc window ID must be set before opening display

** (pipeviz:26034): WARNING **: 14:40:55.014: ximagesrc window name must be set before opening display

I think this is due to the fact that the output window remains active? Not sure however.

You can reproduce it by adding a simple pipeline ximagesrc ! autovideosink

Then press play and make sure a window gets opened. Then try setting the xid or xname property. This fail and you cannot set the properties anymore.
