Hello,

I'm facing the problem mentioned in [1]. Problematic are all examples
with virtual methods.

I have tried simpler example (attached) with same result. There is no
problem, when try same thing with guile-gi library. Somehow, callbacks
are not callable back from C code. Any clue?

I'm using Nix.
