This also seems to be an autopkgtest regression triggered by an
adwaita-icon-theme update. From Lucas' build log:

and so on.

I think this means adwaita-icon-theme has dropped some icons that GTK 3
assumes will be present.

(See also, all the bugs complaining that icons disappeared, most recently
#1005997 - but my understanding is that there is no real specification for
what an icon theme must contain, and consumers of icon themes frequently
assume that every icon theme will have lots of random icons beyond the
baseline set from hicolor-icon-theme.)
