Thanks for the report. It is interesting bug. I found what happens but not yet what causes such a behaviour in this case only. I will keep you updated.

OK, I think I fixed it. It is now in the dev branch. It will be available with the next release. You can try the dev version for now.

Thanks for waiting.
