Yes, that works nicely. When creating the pixbuf at the unmanaged, I
specify a pointer to the (unmanaged) function as the pixbuf's
destroy-notification. That function contains a simple g_free on the
previously allocated memory. When the pixbuf is garbage-collected on the
managed side, this function gets called nicely (though, I don't really
know _WHO_ calls it)

BTW, I'm not using pixbufs to pass the actual playback data (that would
be a performance overkill). I'm merely using them to generate all kinds
of thumbnails & frame previews. When playing, I'm drawing directly to
the XOverlay so I don't need to handle the data on the managed.
