Disk properties in Gnome Files (Nautilus) shows a black chart for disk usage on Ubuntu 22.04

[Marcus Aurelius]

[ Impact ]

if I open the Properties window for a disk (not a plain folder) the pie chart intended to show disk usage is all black (screenshot attached). On previous versions it used to have different colors for "used" and "free" space.

[ Test case ]

1. Open nautilus
2. go to "/" path or to the root of a disk
3. Right-click on an empty area (or in the headerbar) to open properties
4. The pie chart shown should use colors for the used space

[ Regression potential ]

The theme is applied to any other application using a similar widget tree with a drawing area with the '.disk-space-display' class

----

Testing a clean install on a virtual machine gives the same results so it's not an issue related to the upgrade process. I guess it's related to the theming features added to Ubuntu 22.04.

Despite affecting Nautilus from the user's perspective, on second thought I think the bug is in yaru-theme.

[Sebastien Bacher (seb128)]

Which Ubuntu release, theme and variant are you using?

[Daniel van Vugt (vanvugt)]

The missing style is called disk-space-display in nautilus: src/resources/css/Adwaita.css

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Daniel van Vugt (vanvugt)]

The bug is confirmed for jammy, but not in lunar where the pie chart has been replaced with a standard coloured progress bar.

Verification done.

The pie chart works as expected now: main color for used space and some light gray for free space. Unfortunately the small squares next to xxx MB/TB used/free are still invisible instead of indicating the color used for each slice. I don't think this is enough to fail validation, since they weren't in the original bug report anyway.

Version tested: 22.04.5 from jammy-proposed

These seems to use different theming path, can be addressed but I couldn't figure out the proper one.
