I've seen this error only once when I was writing a C++ wrapper for a GObject and
the GObject instance was being unref'ed thus destroyed without the C++ wrapper
being informed. The C++ wrapper later on tried to call an "action signal" on
the invalid instance it had and Glib printed that error.

So it was the C++ wrapper trying to use some garbage memory as the GObject.

I think this also explains the hang because of the invalid memory reference.

Sorry for not being able to help more here.

Cheers,
