[rdiff-backup-users] exception in path [...]/long_filename_data

[Claudio Belotti]

hi,
after several months of good service rdiff-backup started to give
exceptions on my Mac OS X
I don't understand what is causing the error, can anyone help?

I started a new set of backups and it works with no problems but I
wonder if it could be possible to save the old set

This is the output given by the program
