Confirming what Christopher wrote in comment 8: The problem seems to be that apport-cli is now a python3 program, but python-launchpadlib has not been ported to python3. Therefore, it fails.
The workarounds posted so far do not work on raring.
This makes it rather difficult for users to gather system information for bug reports. I would think fixing it would be a high priority.
