I removed the exception statement from:
self.__argData = OpenMaya.MArgDatabase(self.syntax(), args)
The test came up with the following error. 'n' should be an int.

cmds.test(n='d')
# Error: (kFailure): Unexpected Internal Failure
# Traceback (most recent call last):

MArgDatabase should print out an information message for you. Perhaps
you've failed to notice it because of the exception?
You should be able to just trap the exception and return. If you do
that and still don't see an informative error msg, let me know.
