Sorry, I can't figure out where to change the tag. 
I added a comment summarizing my (successful) testing.

 Hello Ian, or anyone else affected,

Accepted xsane into focal-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/xsane/0.999-8ubuntu2.1
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Title:
  ERROR: xsane-startimage not found.

Status in xsane package in Ubuntu:
  Fix Released
Status in xsane source package in Focal:
  Fix Committed
Status in xsane package in Debian:
  Fix Released

Bug description:
  [Impact]

  Starting xsane produces the message:

  ERROR: xsane-startimage not found. Looks like xsane is not installed
  correct.

  It appears that the files in xsane-common are not copied into the location where xsane looks for the file xsane-startimage.png.
  A similar problem was reported in late 2019 for debian.

  [Test Plan]

  You need a focal machine with a connected scanner to reproduce the
  issue.

  * Start xsane from terminal
  * Notice the error message as well as the incomplete UI

  Then install xsane and xsane-common from focal-proposed, and find that
  the issue is no longer present.

  [Where problems could occur]

  The proposed change simply copies a .pnm file to a location where the
  program expects it to reside, and adds a symlink to the docs on disk.
  Can't think of any side effects of these measures.
