My best guess is that it uses FETCH ENVELOPE, which is somewhat broken in
0.99.8 if some headers (subject, in-reply-to mostly) contain '"' characters.
BODY and BODYSTRUCTURE fetches can also break but they're less likely to
contain '"' chars.

Try if the included patch fixes. Dovecot may have cached those replies
already, so delete all .imap.index* files.
