Python error after upgrading from 2.5.1 to 2.6

Failing on one machine, but not the second one I upgraded. Both machines are running Ubuntu 15.10. The machine where it fails has AuFS and bind mounts. Both machines have the same /etc/glances/glances.conf:

[diskio]
hide=ram0,ram1,ram2,ram3,ram4,ram5,ram6,ram7,ram8,ram9,ram10,ram11,ram12,ram13,ram14,ram15

Removing glances.conf or the alias has no effect. Works again after downgrading back to 2.5.1.

@rmenessec The error is on the sensor plugin. As a workaround. Can you try to run Glances 2.6 with the --disable-sensors options?

@asergi Perhaps a issue following the implementation of compat.py script ? Can you have a look, we can schedule an hotfix (version 2.6.1) if the bug is confirmed.

Also getting this on upgrade from 2.5.1 to 2.6. Web view works, --disable-sensors works in console, as does running on a VM (no sensors). I tried hiding specific sensors in glances.conf but that does not seem to be functional - they still show up in web view.

Python is 2.7.6. Ubuntu 14.04, kernel 4.2.

On Ubuntu 16.04 on a Lenovo T440p, glances works in console with sensors enabled, with python 2.7.11.

@nicolargo , that worked. I'm using glances in console-only mode.

[nicolargo]

@rmenessec i just add a workaround in the DEVELOP branch, can you test it ?

[rmenessec]

@nicolargo , seems to work.

I'm finding that glances.conf is mostly undocumented. Should I open a separate bug for documentation?

[nicolargo]

@rmenessec Most of the specific configuration file documentation is in the Anatomy of the application chapter: http://glances.readthedocs.org/en/latest/aoa/index.html

Feel free to open an issue and propose improvement for it.
