That's what I expected. Have a look at the mailing list archive of the
last few days. This (or a similar) problem has occured twice now.

Most probably scanimage is linked against a wrong backend.

Try disabling the line "/usr/lib/sane" in /etc/ld.so.conf and run

That's true. Usually the v4l (video for linux) backend is linked to
the frontend when this bug occurs, but it seems to be a differnt one
in your case. At least the version number is different.

If the above hint doesn't help, try to find out against which library
scanimage is linked (ldd). The check which backend it is in reality
(e.g. strings /usr/lib/sane/libsane.so|grep 'sane_.*_init').
