Fix for #2994 (undefined method "_file" message)

Attempting to call a constructed method name with a nil component
(the checksum type in this case) causes an unhelpful error message
in a case where either 1) the results were not needed anyway or 2)
a more useful error message would otherwise be generated. It also
opens (at least hypothetically) then possibility that some unrelated
method (in this case "_file" would be called if it existed.
