To find out, I've removed it from the inputs and it built just fine and gcm-viewer also started up fine. What was the reason that you added it? > Would it be okay if I leave things as it is for now? You are free to leave it as is on your computer. When merging it to guix master there have to be some standards--otherwise master would be perpetually broken. In this specific case, some other packages in (gnu packages gnome) also have adwaita-icon-theme as input. Even when there is that input that is unused it will not cause problems (however, it will also not do what you wanted it to do--whatever that is). Also, nothing depends on gnome-color-manager. Therefore, applied to guix master as commit 29ae18db0578bbdbc0119703f7412fe91927e80e. But really, having one specific theme (which is by definition a user-selectable thing) as an input is weird. Let's fix that everywhere eventually.
