Well, yes, there is a bug. But how is this happening? > #3 0x004f94fd in settings_parse_keyvalue (ctx=0x99e4050, > key=0x99c42f8 "plugin//etc/dovecot/users", value=0x99c42f2 "yes") Where is this "plugin//etc/dovecot/users=yes" coming from? Is it from a userdb lookup that returns a broken setting? If Dovecot is somehow internally setting this, there's a bug somewhere.
