Corrupted index cache after migrating from maildir to mdbox

I mv'ed all dovecot.index.cache files for one mailbox away but I still
get error messages:

Oct 12 22:47:12 mail01 dovecot: imap(foobar at Error:
 FETCH BODY[] for mailbox INBOX UID 3 got too little data: 738 vs 1543
                                                                Oct 12
22:47:12 mail01 dovecot: imap(foobar at Error: Corrupted
index cache file
Broken virtual size for mail UID 3

So dovecot recreates the cache file but they are instant broken again?
Any thoughts here?
