Dear Maintainer,
Today I tried to restore directory from a backup with deja-dup. The restoration
always failed with the following traceback:
Traceback (innermost last):
File "/usr/bin/duplicity", line 107, in <module>
with_tempdir(main)

lines = output.split(u'\n')
TypeError: a bytes-like object is required, not 'str'
The folder in question is on a secondary, ntfs drive. If I try to restore a
file on the main drive,
no error happens. This is probably because deja-dup does not use the gio
backend in this case.
The following patch fixes the problem for me:
