Fix FTBFS of aptdaemon 1.1.1 for Saucy

The functionality to automatically download and install printer drivers in system-config-printer does not work any more in current Saucy. The problem is with PackageKit. After a hint from xnox on IRC I have installed aptdaemon 1.1.1 from

https://launchpad.net/ubuntu/+source/aptdaemon/1.1.1-0ubuntu1

(adding "DEB_BUILD_OPTIONS=nocheck" to debian/rules to override the failing tests) and with this version the driver package installation of system-config-printer works.

Can you fix the aptdaemon 1.1.1 package so that it makes it into Saucy? I am very grateful if automatic printer driver download will work in Saucy.

The problem seems to be an API compatibility failure when trying to add the GPG key:
