Bug 1424 fixed a crash when doing (Right click)->Apply as filter on a hf_ entry
that was of type FT_INT32 with base BASE_HEX. It was fixed with the comment
"You can not combine FT_INT32 with BASE_HEX."
But it appears many (or at least several) other dissectors use FT_INT32 with
BASE_HEX.
Either proto_register_field_init() should reject registering such a combination
or the underlying bug (filter prep?) should be fixed. (The latter makes more
sense to me but I'm out of time for the moment.)
