dovecot - Jun 2019 - Error: quota-status: Client sent invalid recipient address: Invalid character in path

Any idea what this is?

quota-status(user at example.com)<4975><CLsXEzfSE11vEwAArt9ycg>:
Error:
quota-status: Client sent invalid recipient address: Invalid character
in path

I have this enabled in my config

service quota-status {
  client_limit = 1
  executable = quota-status -p postfix
  unix_listener /var/spool/postfix/private/dovquota {
    mode = 0666
    user = postfix
  }
}

this is given by the address validation routines (for example see
lib-smtp/smtp-address.c as a starting point).

Maybe it would be easier to approach it by looking at the email address
that gave the error.

Is the email address compliant to smtp standards? Does it contain utf8
characters? Does the email address correspond to a mailbox of the same
name with a quota to be checked?

It is not just one email, the logs were full of them but I think I found
the source of the problem. When I build from sources, libicu for FTS
unicode normalization was checked. I have rebuild yesterday without ICU
and no errors like those so far.
