"DBERROR: error listing log files" if only skiplist

[Marco Broglia]

I have cyrus-imapd v2.3.12p2, and no db with `berkeley' in imapd.conf. 
Then, every checkpoint period (now I have 30m), the following errors 
appears in log (3 times):

[...] ctl_cyrusdb[42037]: DBERROR: error listing log files: DB_NOTFOUND: 
No matching key/data pair found
[...]ctl_cyrusdb[42037]: DBERROR: archive /cyrus/imap/db: cyrusdb error

I try to set duplicatesuppression with berkeley and they disappeared.

I check the source and see that without any berkeley log files in 
`/cyrus/imap/db' the errors is sure.

I think that it could be easily solved, or do I miss something ?

Follows the db part of `imapd.conf':

  - annotation_db: skiplist
  - duplicate_db: skiplist (duplicatesuppression: no)
  - mboxlist_db: skiplist
  - #ptscache_db: berkeley (I don't use it)
  - seenstate_db: skiplist
  - #statuscache_db: berkeley-nosync (I think I don't use it)
  - subscription_db: flat
  - #tlscache_db: berkeley-nosync (I don't use it)

Bye.
Marco.
