indicator-cpufreq sets a bogus icon theme path

[Alistair Buxton]

To reproduce:

    install Xubuntu 18.04
    Open appearance settings.
    Select a theme that makes panels a light colour.
    Select ubuntu-mono-light icon set.
    Install the package indicator-cpufreq
    Open a terminal and run "indicator-cpufreq"

Result:

    The indicator will be rendering using the -dark icon set (designed for dark panels.)

This happens because indicator-cpufreq sets a custom icon path which does not point to any icons. This causes the fallback icons from the hicolor theme to be used instead, and those are the dark variants.

On closer inspection it turns out that the icon is being drawn at the right size. It looks funny because the wrong variant has been selected: light icon on a light panel. status notifier does not seem to be able to select the correct variant.
