I get exactly the same error with 1.4.1-2. I notice, though, that on upgrading to Pangolin, packagekit ends up not being installed (and zeroinstall-injector recommends but does not install it).
Attempting to install packagekit yields this; the second problem is likely just a mirror glitch (mismatched release numbers) but I'm not sure about the python-aptdaemon.pkcompat and packagekit conflicts -- looks like Ubuntu at some point switches to "providing" PackageKit APIs using this APT Daemon? I'm traveling until the end of the week and my Internet connection is rather spotty; I'll try and look into aptdaemon next week unless you get there first. Thanks!
