[rdiff-backup-users] restore old backups fails with gzip error -

[Hunter Matthews]

All, 
    I need to restore this one file from rdiff-backup, and am
consistently getting the following error from every backup so far.

I've checked the logs of when the rdiff-backups were made and no 
errors were reported - any idea whats going wrong?



address@hidden postgres]# rdiff-backup -r 2005-05-10 AFTOL-2.custom
