Sane has errors

So, I've started on the move about of SANE calls as described in an earlier post. However, I'm still getting problems in some simple scenarios.  I've isolated these out into their own very simple program so they can be demonstrated.

• https://github.com/clearscene/opendias/blob/d5245ca30ee4cbd7bc78bf8fa287debfe16944b3/contrib/makeGetScannersText

And as a result, I've raised a new bug against the sane project.
