[Dovecot] Dovecot returns everything starting with "." as folder

Hi,

I'm using dovecot imapd 0.99.10.5 from debian unstable and I noticed that dovecot returns everything in the maildir folder that starts with a "." as a folder as the result of

LIST "" "%"

command without checking if it is really a maildir folder (must contain the directories cur, new, tmp and the file maildirfolder).

This is a little bit annoying because it also returns Sylpheed's cache files '.sylpheed_cache' and '.sylpheed_mark' if they exist in the maildir.
