[Dovecot] Maildir and Invalid data in file

I'm using dovecot version 1.0.13 on reiserfs on hardware RAID-0, but I'm getting the
following error in the logs every time one user tries to access his old mails in the .Sent

dovecot: 2008-06-23 15:09:46 Error: IMAP(marek.chajecki): Invalid data in file

As a result he fails to get access to the emails in this folder.

I've googled a bit and read that deleting the uidlist makes dovecot recreate it, but after
some time the same thing happens. It's a new hard drive, so I don't think this is a hard
drive fault.

Some additional info: this server is being used by about 200 users who get about 100
emails daily each one of them.

Any help will be appreciated!
