The error occurs b/c the bundle in question defines constraints as a dict instead of a string. While this is clearly not deployer's fault, it would be simple to support constraints as list or dict, and in fact the official docs (https://jujucharms.com/docs/devel/charms-bundles#service-constraints-in-a-bundle) already claim that a list will work.
