Your problem here is that the 'seen' database, which keeps tracks for 
you which emails you have already read, has become corrupted. The 
easiest thing you could do would be to simply stop cyrus, remove the 
file /var/imap/user/b/bob.seen completely, and start cyrus again. It 
will cause cyrus to create a new database and afterwards will keep 
proper track again.
The reason your database got corrupted could for instance be that the 
/var-filesystem become full sometime ago: this is what caused a lot of 
our seen-databases to become corrupt.
If there is a lot of information in your seen-database you could also 
attempt to 'repair' the database by removing the corrupt transaction at 
the end. We did this and it works fine but is a bit awkward. For more 
information, please see e.g.
