Hey, sorry for not anticipating this possible problem.

The option is documented here:
https://developer.gnome.org/gtk3/3.13/gtk-update-icon-cache.html
I'm pretty sure I included the documentation update when
cherry-picking the patch to the 2.24 branch too.

As Emmanuele said, no experimentation here.

The change itself is pretty harmless. GTK+ (2 as well as 3) is
entirely capable of working with image-data-less icon caches. The one
place where we require image data to be present is the builtin cache,
because the icons are not actually present anywhere else on the
filesystem.

Again, sorry for the inconvenience,
