To answer myself: this is a problem in the Swig interface. The error is 
not supposed to be an error that is reported to the user, but it is 
because it is there. The problem is in cpl_exceptions.i, which does not 
work (at least) in this case. I don't know how to fix it right away. 
Kevin, Charlie: this is probably also a bug in Python and Ruby 
interfaces. The %exception should not just blindly test eclass but test 
the return value from the function.
