How to repair a broken seen state file

[Gary Mills]

I'm seeing errors like this regularly in our messages log:

  Jul  4 11:43:37 castor imap[16398]: [ID 514311 local6.error] DBERROR: skiplist recovery: 058C should be INORDER
  Jul  4 11:43:37 castor imap[16398]: [ID 729713 local6.error] DBERROR: opening /imap/conf/user/O/inqarts.seen: cyrusdb error

It's always for this one file.  All the others are fine.  It's a
skiplist database.  The ownership is correct.  A reconstruct on the
mailbox has no effect on the file.  Can I just remove the file, with
no ill effects?  Can I fix it somehow?  We're running cyrus-imapd-2.3.8.
