Do you send a NULL window with set_xwindow_id? Did you try to change
the window directly? IIRC glimagesink reparents its window into the
xoverlay one. If you send a null window it's likely that when you set
a new window it tries to reparent it to null. I'm not sure if this
reparenting thing is right, other sinks create a new context with the
new window. Anyway, if what I'm guessing is right, glimagesink should
at least check for the xid to be non null.
