doveadm(user): Error purging namespace

Hi

I have an issue with doveadm:

doveadm(user): Warning: mdbox /home/user/mdbox/storage: Inconsistency in map index (227,40 != 227,56) doveadm(user): Warning: fscking index file /home/user/mdbox/storage/dovecot.map.index doveadm(user): Warning: mdbox /home/user/mdbox/storage: rebuilding indexes doveadm(user): Error: Purging namespace '' failed: BUG: Unknown internal error

Why does this happen and how can it be resolved? User is using thunderbird as the mail client.
