Since loading an icon theme can take a couple of seconds on old computer, it might be usefull to show some loading indication. Possible options are: - Throbber icon centered in the icon chooser dialog - Watch (busy) cursor for the iconview window (like gtk file chooser) - Progressbar inside the dialog (not a good idea tho)
The icons are not loaded by the icon selector on "startup", so that doesn't apply here. Instead the icons are loaded on demand (using the thumbnail database to avoid rendering SVG all the time).
Resolving to INVALID.
