Copy kerning values from group to group?

Hello, the @Tosche 's script “Copy Kerning Pairs.py” does not work in G3 :cry: :cry: :cry:
On macro panel I read

Copy Kerning Pairs Error: ‘NSKVONotifying_GSFont’ object has no attribute ‘kerningDict’

In case, anyone knows an alternative script/way to do the same?

I’ve send pull request on github to Toshi. In the meanwhile here you can try use the version from my forked github repo.
tell me if it works, I haven’t tested throughly

well, it runs but it doesn’t work at the end. Kerns are not copied
