This seems to have nothing to do with master account or not. Does this happen if you try to open the virtual mailbox again?

Hello,
I am running dovecot 2.2.34 (874deae), on Debian stable, from backports.
I just tried the master account, and although everything worked in the email client, I had logs in the error logs:

I attach my dovecot configuration too.
Thanks for your help.
