Actually, not true: I found that
@item.tags.size was responsible - tags is an array! If I use @item.tags.length it works. Now I should clearly be able to use "size"? I use it with other variables in the same context and only this one barks. Latest ruby-1.9.2 (maybe that's the problem? It worked a few days ago.)
