Bug description:
  [Impact]
  A bug in the SANE Kodak driver can cause a SANE device scan to crash the client that is using it (e.g. colord, simple-scan).

  [Test Case]
  1. Run a SANE client on a system that is failing Avahi scans (exact cause not determined).

  Expected result:
  Client works without crashing.

  Observed result:
  Client crashes.

  [Regression Potential]
  Code fix could cause a change in behaviour of successful Avahi scans for Kodak devices, though the fix matches the Avahi documentation for correct usage.
