The "netcdf.grid" is just our internal identifier for the data source type. 
I've changed it so it will show as "file.grid"

Now, that said - what is going on is that when we access the grib file we 
create an index of the products and that is breaking. When accessing files via 
http we kind of treat the web server as a random access file. The indexing must 
be trying to read more than what's there.

I'll move this ticket over to our java-netcdf group (which does the grib work) 
and they will look at it.
