Well, yes, it should work. That's indeed a problem with the
getsubdtype method of the converter.
The problem is that we need to estimate the datatype of the output of
the converter. In most cases, trying to convert '0' works properly,
not in yours however. In r6338, I force the type to object if
converting '0' does not work. That's a patch till the next corner
case...
