[rdiff-backup-users] Is this really an I/O error or what?

[John covici]

Hi.  I upgraded a system from etch to Lenny and so the rdiff backup
went from 1.1.15 or maybe an older version to 1.2.5 and the first time
I ran it, I got the following output:

Exception '[Errno 5] Input/output error: '/backup/usr/share/doc/debconf''

How can I fix this, or is it really a bad hardware?

Thanks much in advance for your assistance.
