Unbound obtains DNS data but fails to report it / return it

I have a new opensuse 13.2 machine I’ve installed unbound 1.5.4 on.  I installed it from source as I couldn’t get the opensuse rpm to work.  But then, I can’t get this one to work either.  That is, I get a non-response.  Unbound goes and looks but fails to report the answer because apparently it cannot validate.  

 

I’m completely stumped.  Any ideas?

 

Here is the relevant portion of the logs – verbosity 4.  I ran
