Hello there Brian, and thanks for this bug report!

traditionally, dependencies go "top-down"; from tools to libraries, and from 
generic utils to backends, not in reverse. For example, libsane1 is 
effectively useless on its own on my laptop; and it doesn't depend on sane-

So, this missing dependency doesn't
* makes the package in question unusable by most or all users, or
* causes data loss, or
* introduces a security hole allowing access to the accounts of users who use
  the package
(definition of the "grave" severity).

It _does_ make it a no-op, and useless, but not "unuseable", I'd argue. Also, 
the side-effect of a "grave" severity is that it makes the package subject to 
auto-removal from the next stable release, as "release-critical bug". In other 
words, such a severity marks a package as unfit for release (== the release 
would be better off without this package, rather than with this bug). For all 
these reasons, an "important" severity seems much more adequate (to me).

All this said, I think it's a valid bug, and I'll therehore add a sane-utils 
"Recommends"; this will pull it by default, but not enforce it.

Best regards,
