    https://github.com/apache/brooklyn-server/pull/672
  
    I have **finally** got round to doing a test on this, sorry to have taken 
so long. 
    
    I will attach a couple of zip files here for test purposes, each being a 
separate -SNAPSHOT revision of a simple blueprint. The second builds upon the 
first, getting a bit more complicated.
    
    My first test zip file causes an error when I try to upload it; what you 
see on the command line is 
    
        br catalog add file://$(pwd)/test672a.zip
        json: cannot unmarshal string into Go value of type 
models.CatalogEntitySummary
    
    and in the Karaf log you get

    I tested the same file against `master` and it loads ok there, so I think 
there is something in the PR to cause this. 
    
    I will see if I can make a bit of time next week to look at this again and 
investigate what's going on.
