Indirection symbol name inappropriately compared to string

When I startup Puppet under Puppet Server, I've noticed messages like this one:

2016-03-29 08:44:49,364 WARN  [clojure-agent-send-pool-7] [puppet-server] Puppet Comparing Symbols to non-Symbol values is deprecated

   (file & line not available)

Tracing the source of the message, it appears to be happening, at least in one case, due to this comparison:

https://github.com/puppetlabs/puppet/blob/master/lib/puppet/indirector/terminus.rb#L73

In this case, the previous line does a .intern call to produce the indirection_name. Since the result would produce a symbol, it seems like the comparison above should only compare for an empty symbol - maybe something like...

if indirection_name == :""

  raise Puppet::DevError, "Could not discern indirection model from class constant"

end
