  Those types are GBoxed, and the wrapping doesn't allow advanced
equality checks (basically GBoxed only allows you to register 'copy' adn
'free' methods for those cheap objects). You would have the same problem
as the C level (i.e. you'd need to compare the contents to see if
they're equal).

  fwiw, this will also apply for the other 'boxed' classes in
gst-python: GstPlugin, GstStructure, GstTagList, GError, GstData,

  Patches welcome to fix that, it would be very nice indeed. It looks
like that could be done by overriding the tp_compare or tp_richcompare
slots in the override files.
