I manually clobbered all files in my installation that contained the word "sane" or were in "sane" directories, and re-installed the back- and frontends, but the problem with the preview persists.
But as the scanner is slower in preview mode than in normal scan mode at low resolution, it might be a good idea to map the preview option to some low-res option in the backend. Another (although theoretical) problem with the Epson/Snapscan backend: The backend reads the path of the firmware file from the snapscan.conf file. What happens if there is more than one scanner?
