When selecting a dataset from the search in the data tab and hitting "Download Files" with the default filter "*.nc" I get an internal server exception and the following exception (this does not happen at JPL which also has 1.3RC2):

Server Port: 80
Server Name: albedo2.dkrz.de

This seems like a problem with the registry, I'll see what I can find.
