Yeah, it should.  This *may* be a safe change to make wrt existing
programs - a program that expects to see the exception should still work if
the code is changed to return an empty list.  However, it is possible things
will break (eg, the code could be written to assume the list has at least
one entry when no exception is raised.

Feel free to open a bug at sourceforge, but I'd welcome any comments...
