It works for me. I did make a change to the add_icon() function to avoid empty icon names, but it works without that change.

Here is the booklist:

The icons are on the author column.

Here is the cc_icons folder:


Here is the icon rule screen:


And here is the template, which is the same as yours except the one change mentioned above and changing the 'uk.png' icon name to 'beautify.png':

program:
	def add_icon(icon, val):
		if ! val then return icon fi;
		if icon == '' then icon = val else icon = icon & ':' & val fi;
		return icon
	fed;

	icon = '';
	if $languages == 'eng' then icon = add_icon(icon, 'beautify.png') fi;
	icon = add_icon(
		icon, 
		switch(
			$$#toread,
			'true', 'toread.png',
			'false', 'false.png',
			''));
	if $$#formats == 'paper' then icon = add_icon(icon, 'paper.png') fi;
	if $$#read == 'true' then icon = add_icon(icon, 'ok.png') fi;
	if $$#source == 'geniallokal' then icon = add_icon(icon, 'geniallokal.png') fi;
	if $$#source == 'wbg' then icon = add_icon(icon, 'wbg.png') fi;
	if $$#readinglist != '' then icon = add_icon(icon, 'reading_list.png') fi;
	if $$#annots != 'NONE' then icon = add_icon(icon, 'annotations.png') fi;
	if list_count($authors, '&') > 1 then icon = add_icon(icon, 'series_authors.png') fi;
	return icon

One possibility: you can't use == for multi-value columns. If #formats or #source is tags-like then you must use 'inlist'. as this:

if 'paper' inlist $#formats then icon = add_icon(icon, 'paper.png') fi;
