Check your vfuncs. That's what I would suggest at first. You can try
commenting them out completely to check if they are the problem.

I notice that you have some conversions for vfuncs or signals in the
main .m4 convert file, but you should really put them in the .hg files
to avoid using them for regular methods and to make sure that they use
the correct reference counting.
