[rdiff-backup-users] AssertionError: Path

[Jure Pecar]

Hello,

We are using rdiff-backup do nightly backup our servers. The system of shell 
scripts was set up by previous admin around version 1.1.5 and it has worked ok 
until now.

A few days ago I noticed that one of the machines is not being backed up. Upon 
further inspection I discovered some errors from rdiff-backup. Since google did 
not turn up anything meaningful, I deceided to upgrade to 1.1.15. But 
unfortunately the error persists:

Sorry, something went wrong
Fatal Error: Lost connection to the remote system


File with inode 4392511 turned up to be a small jpg image, not suspicios in any 
way.

Any ideas?
