[rdiff-backup-users] Backup fails with OSError 5 because rdiff-backup inverts file name casing?!

[Ben Tebulin]

Hello there,

I desperately want backup my Linux computer. And I want to do it safely.
Therefore I created a reverse EncFS mirror of my root directory. I
mention this, because this causes directory/files to backup containing -
and , in their names.

Now, if I try to run:
    rdiff-backup --include '0l5Nvypf79eTb,' --exclude '**'  \
          /mnt/encfs address@hidden::/home/backup


rdiff-backup fails with:
   OSError: [Errno 5] Input/output error: '/mnt/encfs/0L5nVYPF79EtB,'


Now look closely:
             --include '0l5Nvypf79eTb,'
    vs.     '/mnt/encfs/0L5nVYPF79EtB,'

"Sure you won't find that file! You inverted the letter casing?!"

Anybody a hint where this happens inside the code? And why?

Thanks
- Ben


P.S.: Anybody still maintaining the code at all?
