[rdiff-backup-users] Warning: Cannot find SHA1 digest for file .... perhaps ..

[Robert Nicholson]

Warning: Cannot find SHA1 digest for file usr/share/terminfo/73/sune,
perhaps because this feature was added in v1.1.1

it says this for every file

So why would this error come up when I'm doing a verify immediately after the 
backup I just did and this
is currently the only backup I've done.

I'm using rdiff-backup 1.3.3

why would it not create digests after the first backup?
