This failure seems to have been introduced by the latest verion of iris-grib. The points of one of the dimensions is reading [0.] rather than [~2.] .

This is actually related to this issue: SciTools/iris-grib#150
When the suggested changes are applied this test passes again.

path = tests.get_data_path(('GRIB', 'reduced', 'reduced_gg.grib2'))

gribapi has changed where GribInternalError is stored. Fixing this solves 8 of the 10 errors in the grib tests mentioned in #3447. I've decided not to handle the possibility of both cases since the updated version of iris-grib is the only one which is compatible with python3.
