CORBA doesn't support dictionaries.

One way to transfer python dictionaries across CORBA is to convert the
dictionary to a sequence of CORBA structs, where each struct represents
a (key, value) pair.  The dictionary can be reassembled from this at the
other end.

You can see which types are available for use with CORBA by checking out
section 3.11 of the CORBA spec:

... and you can figure out how these CORBA types map to python by
checking out section 1.3 of the python language mapping:

Luke.
