Comment 2 for bug 662442

I have this problem during verify as well. I can work around this by specifying subdirectories, for example,

ubuntu@ubuntu:/media/1b[...snip...]a1/home/chris$ duplicity --verbosity info --file-to-restore "Documents/" --archive-dir /media/CHFOO_FAT32/backups/duplicity-cache/ verify file:///media/CHFOO_FAT32/backups/backups-laptop/ Documents/

It might be possible to list out the files (list-current-files) in the backups and iterate through them while specifying the filename to the --file-to-restore argument using a script for files that can't be restored in a specific directory without this error.
