Ubuntu SDK does not install on clean 12.04 LTS (64bit)

I have a VM of a clean 12.04 64bit - taken from our Continuous Integration system so it is a tried and tested VM. However, when using it and following the instructions on the site (http://developer.ubuntu.com/apps/create/get-the-sdk/) it fails to install. I have mangaed to track down the failed dependencies to this:

$ sudo apt-get install qtdeclarative5-ubuntu-ui-toolkit-plugin

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies.
qtdeclarative5-ubuntu-ui-toolkit-plugin : Depends:
qtdeclarative5-unity-action-plugin (>= 1.1.0)
but 1.0.0bzr25precise0 is to be installed
E: Unable to correct problems, you have held broken packages.

I have found that there is a 2.8.1.2bzr90precise0 here :
    https://launchpadlibrarian.net/166279521/qtcreator-plugin-ubuntu_2.8.1.2bzr90precise0_amd64.deb

However attempting to install this results in:

The documentation suggests that the SDK is compatible with 12.04, so how come it can't be installed with a clean VM? Am I missing some other dependency that is not included in the documentation? Is the PPA broken?
