Summary: sane reports that my scanner, which was working fine before I did some Ubuntu upgrades, now possesses 0 scanning capabilities. This is a bug on someone's part, and Ratcliffe suggested I try here. (I got no replies in the IRC channel.)<br>

It looks as though the SANE backend process is not finishing<br>
