How to defeat SHA1 hash mismatch when trying to restore a backup in duplicity?

Question

linux

Actually the subject,
when restored, issues

# duplicity -t 3D --force restore file:///backup/vhosts/ /home/restore/

Last full backup date: Sun Mar 22 22:07:29 2015
Invalid data - SHA1 hash mismatch for file:
duplicity-full.20150322T220729Z.vol16.difftar.gz
Calculated hash: f225519ed7c773b418cd1697e3010e343bb79fad
Manifest hash: d2b34a36ff6c80c5dbbc9aaf27d927439f86bcd5

the file itself is normal

# gzip -v -t duplicity-full.20150322T220729Z.vol16.difftar.gz
duplicity-full.20150322T220729Z.vol16.difftar.gz:        OK

In Google I could not find a clear answer on how to get around this problem. Does anyone have experience and know how to solve the problem?
PS
OS: CentOS-6, x64. duplicity-0.6.22-3.el6.x86_64
full backup was done like this (once a week)
# /usr/bin/duplicity --no-encryption --volsize 1000 full /vhosts/ ssh://backup:[email protected] example.net/vhosts/
incremental (once an hour)
# /usr/bin/duplicity --no-encryption --volsize 1000 incr /vhosts/ ssh://backup:[email protected]/vhosts/
