Bug Description

When the dbus session isn't set in the environment (which appears to happen when run via deja-dup), the call to the ensure_dbus() in the gio backend fails. This happens when using duplicity on Python 3.0+ as subprocess.Popen.communicate() returns a tuple of bytes objects rather than strings.

Versions:
Duplicity: 0.8.06
Python: 3.7.5rc1
OS: Ubuntu 19.10
Targetting: local mount of SMB share

EDIT: tested on 0.8.06 as well

Please upgrade to the current version of duplicity, 0.8.06. This will assure that any bugs fixed since your release are available and may fix your issue.

NOTE: This applies especially to duplicity versions between 0.7.03 and 0.7.14 inclusive. There was a fix in 0.7.15 that reduced memory usage drastically, and will help with memory errors and inability to start new threads.

There are four options:

* Release tarball Install - https://launchpad.net/duplicity/+download
* Daily duplicity builds - https://launchpad.net/~duplicity-team/+archive/ubuntu/daily
* Stable duplicity builds - https://launchpad.net/~duplicity-team/+archive/ubuntu/ppa
* Stable snap builds - “sudo snap install duplicity —classic"

NOTE: UNinstall duplicity first if it was installed via the distribution repository. For Ubuntu, that would be "sudo apt-get purge duplicity".

This definitely is still an issue on version 0.8.06, tested by installing from the tar.

It still works from the command-line for me on 18.04 and MacOS. Deja-dup must be doing some odd stuff.
