I am attempting to use the 4.6 version of the netcdf reader to process a 
Lambert Conformal file. I receive a rather cryptic exception that prevents me 
from seeing the coordinate system or any feature types and I'd like to know, 
what if any information I could add to the netcdf file to be able to process it 
successfully. Here is the stack trace. Thanks in advance for any help in this 
matter. The file I am processing does have a Latin1 variable defined, so the 
error message is not helping me understand what to do to remedy the situation.
