Comment 1 for bug 1122887

Thanks for reporting this, it turns that they didn't want to go back into shape after all.

So, we use boolean label expression "natty && private" to select restricted slave, it used to work well, but after some recent changes it's unable to startup new slave, but picks up existing slaves with these labels. Issue like that were known with previous version of EC2 plugin, but with one of recent versions, I tested it to work well, that's why I used it. Well, it doesn't, so better really switch to single-term tag usage ("ec2-private").
