python3: setDefault() causes "Segmentation fault (core dumped)" error

[cleary]

Ubuntu Release: 12.10 (quantal)
Package: python3-cups 1.9.62-0ubuntu1
Python: python3 3.2.3-5ubuntu1

When I attempt to call setDefault('printername') on my cups connection object, I get a seg fault message:
"Segmentation fault (core dumped)"

I can do other operations on the object, such as getPrinters() and getDefault().

I've attached an example program that demonstrates the functioning object, and the segmentation fault - you;ll need to change the cups user in __main__
