Many thanks for the explanation! That helped a lot to track down the
problem. Removing the Breaks and Replaces python-cupsutils from
python-cupshelpers lets the upgrade work for me as expected: 

The following packages will be REMOVED:
  hal-cups-utils
The following NEW packages will be installed:
  cups-pk-helper python-cupshelpers system-config-printer-udev
The following packages will be upgraded:

Since we don't have any file conflicts we simply let the autoremove
handle the removal of python-cupsutils. Would this be an acceptable
solution? If so I'd be happy to upload a new version.
Cheers,
