Lubomir, Dan, I found what triggers this issue. I don't know what the reason is, though! It has nothing to do with NetworkManager.
The trigger: 1) I load openvpn cert as zipped tar archive to root. 2) I uncompress/untar the archive that creates /etc/openvpn directory with openvpn cert/config files, user = original user. There is no way back at this point. Whole system is corrupted. It does not help deleting /etc/openvpn directory and note that it is not needed to start openvpn service to get this triggered. Only way I have found to recover is re-install whole system! I'm somewhat worried how easily one can corrupt whole Linux system - just load files to /etc whose user is not a proper user of the installation! They can be loaded to other place, change owner there and load then tho /etc. Anyhow this is none of your worry, I suppose.
