New description:

 The 'Storage Server' page ({{{/storage}}}) of a node running the S3
 backend gives a nevow traceback with the following exception:
 {{{
 /home/customer/LAFS_source/src/allmydata/web/storage.py, line 90 in
 data_last_complete_bucket_count
 88
 89    def data_last_complete_bucket_count(self, ctx, data):
 90        s = self.storage.bucket_counter.get_state()
 91        count = s.get("last-complete-bucket-count")
 <type 'exceptions.AttributeError'>: 'NoneType' object has no attribute
 'get_state'
 }}}

 This happens because the S3 backend doesn't support crawlers, so it
 doesn't initialize the bucket_counter state. This doesn't affect the LAE
 servers because they don't run a web interface, but it should be fixed in
 order to merge the S3 backend.

Comment:

 The leasedb+cloud backend merge supports crawlers, so this ticket is
 unneeded.
