So it turns out + isn't one of the escaped characters... but perhaps it should 
be.

Can you try this and see if it helps?

    conditions: {has_dccs: code.gsub('/', '\/').gsub('+', '\+')}, star: true

Another possibility is it's the wildcarding of words that's getting in the way. 
Try it without star: true too.
