glances crashes with utf-8 decoding related problem

[Alejandro R. Mosteo]

This is a 15.10 fresh install, although the user has a home partition saved from previous installs. Note that creating a fresh user shows the same problem, however.

When launching glances this happens:

$ glances

Also, this happened right after system installation and after a dist-upgrade plus reboot.
