Comment 5 for bug 1220425

There is a 1.4.0 package for Precise in my PPA:

  https://launchpad.net/~fmarier/+archive/ubuntu/ppa?field.series_filter=precise

I'm not maintaining that backport anymore because I no longer have any 12.04 machines, but you're welcome to use it, it's not any less maintained than the unmaintained package that's in the official archive for Precise :)
