Eric,

The EPSG folks deprecate a code when they realize there is a serious error
in the definition (proper name, parameters, etc).  The deprecated code and
it's dependencies remains in the database, but the fixed version is created
as a new code and people are encouraged to use that.

I don't see any reason a code being deprecated should cause g.proj to crash.
This is likely due to something else.

Best regards,
