CA path error, file does not exist

starting with my update to rc1 my system logs get flooded with error "CA path error, file does not exist:MyUserName/openssl.cnf" where MyUserName always is the name of my user, never another customer (probably as they never logged in since the update)

I did never have this message before but I found some info in the forums from years ago that this might have to do with self-signed certificate generation. Probably this is now an issue with letsencrypt-Implementation?

//Edit: Probably I should have stated that I am not using self-signed or letsencrypt at all... I have some websites configured which are using trusted certificates from public CAs, I pasted keys and certificates into the corresponding fields in ISPC so there is no need for the cronjob to create certificates for any of my websites. Cannot speak for customers...

//Edit 2: Oh! And I do not have any websites assigned directly to my admin user at all. I created some dummy customers for my websites...
