[netCDFDecoders #UKB-233671]: problem decoding grib2 2.5 grad

[Unidata netCDF Decoders Support]

Olivier,

i tested the code on the files that you suggested and they appeard
to decode fine.  maybe you could tell me what file and parameter
you are having the problem with so i could test it. As i said 
before there are many different paths to test, so a good test
case would help find the problem.
