Try it again (make clean), I think has Martin fixed it recently. It
works for me.

I really don't know what to do with this issue, I can't test it and I
don't have any idea what should I test.

both should work now

Library is initialized only when you switch to 3D for the first time,
it should be initialized every time

I don't have any experience with volume resolution in grass, so I
really don't know what's happening.
Could I get this data to test it?

This works for me. Can you see any error message?

This is quite weird because in wxpython documentation this method
really exists. Maybe it could be some problem with versions. I tried
another method, hope it works.

Please, could you update the list of known issues on wiki?
