Hi Stephen, Please try my SANE Release PPA: https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-release .
If your scanner is working with this, please try my inofficial test ppa: https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-test . Other users reported similar problems with their scanners. I suppose a problem with one of the recent commits to the git repository. Hope this helps.
