Application: systemsettings5 (5.8.5)

Qt Version: 5.7.1
Frameworks Version: 5.29.0
Operating System: Linux 4.9.0-1-MANJARO x86_64
Distribution: "Manjaro Linux"

-- Information about the crash:
While conducting a system wide update on Jan 17, 2017, I received the following error after all packages were downloaded and installing:

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/bin/powerline-config", line 11, in <module>
    from powerline.commands.config import get_argparser
ModuleNotFoundError: No module named 'powerline'
Traceback (most recent call last):
  File "/usr/bin/powerline-config", line 6, in <module>
    from powerline.commands.config import get_argparser
ModuleNotFoundError: No module named 'powerline'

Now for some reason it thinks that the "powerline" package does not exist, when in fact I verified that the package was not only installed it was at it's latest version.  Anyway, once I ran into the above error the entire update process crashed and refused to continue the update. I will be rebooting my machine and attempt to re-initialize the update process again.
