I recreated the failing OpenVPN connection and I can't reproduce the 
problem anymore.
I thus closed the upstream issue and dropped the forwarded meta data.

My recommendation, if you can still reproduce the issue, is to file the 
issue upstream [1] yourself. It's likely that upstream has further question.
