New Salt version break

I started getting these error messages last week and I discovered it was actually caused by an incompatibility between the new version 2014.01 and an old server 0.17. In general if you’re finding strange errors, particularly with configuration that used to work, double check your version numbers match. You can always do a ‘salt machine test.version’ to check the clients version.

salt machine state.highstate
machine:

	State: - no
	Name:  	states
	Function:  None
    	Result:	False
    	Comment:   No Top file or external nodes data matches found

Or via salt-call state.highstate
