Hi Ralf,
Thank you for taking the time to report this bug and helping to make Ubuntu better!
I experimented with openvpn on 16.04 this morning and never hit the issue in my cases.
To help debugging it could you either share more of your config and provide the crash data that apport should have catched on that crash.
Should be "apport-collect BUGNUMBER" so in this case "apport-collect 1559600"
This will process the crash that should be in /var/crash/ and upload it to that bug.
