I was automatically entering the correct password which results in the above.

Below is what happens when the password is incorrect.

 %scanimage -L
Password for root on localhost? 
Failed cupsGetDevices
device `pixma:04A91908' is a CANON Canoscan 9000F multi-function peripheral

...so I rebuilt sane-backends without CUPS support (which defaults to ON in 
the config). and it now works just fine.

The problem is my CUPS config although in all other respects CUPS seems to be 
working just fine so I'm not sure where to look for that.

I've been scratching my head all day over this and now the "solution" comes 
once I have to explain to someone else (plus a serindipitous mistake)

Pointers to a more complete/correct solution will still be appreciated, 
especially if it helps others find a better search result than I managed to 
find.
