Missing symbolic icons in settings

[carbonatedcaffeine]

Could be related to #88, except I am not experiencing that issue myself.

I also found a missing icon in Gnome Software.

I discovered this is due to the icon theme being set to hicolour and not adwaita.

strange, that would indicate that the hicolor icon theme is missing icons?

[m-weigand]

i.e., that gnome ships with a broken hicolor theme?

I changed the icon theme back to Adwaita for the next build. Existing users, however, must change the icon theme manually in the "tweaks" application (submenu "Appearance"). thanks!
