I have this same problem. Based on FransSchreuder solution, I found a temporary workaround:
I extracted the file: libsane-genesys.so.1.0.23
To directory: /usr/lib/x86_64-linux-gnu/sane/libsane-genesys.so.1.0.23
From package: libsane_1.0.23-0ubuntu1_amd64.deb
This avoid problems with package dependences. And my scanner is now working again in Ubuntu 14.04
