I'd say as a quick fix for stable check that card is not NULL in

the far better alternative.

Getting rid of the file is definitely not a bad idea but I'd still like
to see us make the dummy component more consistent with other components
in order to minimise the chances that we'll run into other special

Right, I do see that we need dummy component to be fixed up. Today if we use dummy twice in a card it refers to same instance whereas IMO it should create separate instances. I will try something on these lines in next month or so...
