Failure in folders with names in UTF8 (Brazil/Portuguese pt_BR)

If I set security backups using the tool DejaDup in Ubuntu and any file or folder names in use 'pt_BR' end up with the below error:

Traceback (most recent call last):
  File "/usr/bin/duplicity", line 1411, in <module>
    with_tempdir(main)
  File "/usr/bin/duplicity", line 1404, in with_tempdir

    globals.archive_dir).set_values()

    log.Debug(_("File %s is not part of a known set; creating new set") % (filename,))
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 4: ordinal not in range(128)

I have found that adding the following line in the / usr/lib/python2.7/dist-packages/duplicity/collections.py the error disappears and the backup is done successfully:

_ = t.lgettext

Same seems to exist problem on Debian/testing, package "duplicity_0.6.23-1_amd64".
This one could be related: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=744064

[David Dahlberg (david-dahlberg-fkie)]

Bug #1286845 looks pretty similar, too. Yet the problem seems to be deeper (or more "prints" are affected than just the one mentioned there): Upgrading to 0.6.23-1ubuntu4 did /not/ help here.

[Michael Terry (mterry)]

This is fixed -- that line is now:
                log.Debug(_("File %s is not part of a known set; creating new set") % (util.ufn(filename),))
Where the util.ufn will translate the filename to proper unicode.
