mmm, this seems to be the same problem I get with GStreamer. One thing is the API object we map (GdkDisplay) and another the concrete implementation in a given environment (GdkDisplayX11). My solution was to modify our mapping code to find a proxy of parent type if a direct mapping can't be found. But it is still experimental code, so I cannot recommend it to you.
