Mistyped the above paths, my icons are in
:/icons/hicolor/scalable/actions et.c., not directly in
:/icons/hicolor of course.

And my :/icons/hicolor/index.theme is as follows:

[Icon Theme]
Name=Hicolor
Comment=Fallback icon theme
Hidden=true
Directories=scalable/actions,scalable/apps,scalable/mimetypes

[scalable/actions]
MinSize=1
Size=128
MaxSize=512
Context=Actions
Type=Scalable

[scalable/apps]
MinSize=1
Size=128
MaxSize=512
Context=Applications
Type=Scalable

[scalable/mimetypes]
MinSize=1
Size=128
MaxSize=512
Context=MimeTypes
Type=Scalable
