[rdiff-backup-users] Regression Fails: "IOError: Not a gzipped file"

[Brad Guillory]

Can anyone offer me suggestions about how to fix this problem?  I  
think that the USB drive that I was backing up to went offline during  
a backup operation.  I have since forced an fsck on the filesystem and  
it came up clean.
