digiKam 5 no longer comes bundled with an icon theme, so when running in Awesome WM there are no icons at all. In Configure digiKam → Miscellaneous → Icon theme it simply says "Use Icon Theme From System".
Are there any icon theme packages which can be used with digiKam? Preferably without installing a whole chunk of KDE or AUR packages. There doesn't seem to be any in the optional digiKam deps:
$ pacman --query --info digikam | grep 'Optional Deps'
Optional Deps : kipi-plugins: more tools and plugins
Searching the package repository for KDE icons or themes didn't yield anything obviously usable.
