** Description changed:

  Binary package hint: cups
  
  IMPACT: lpstat on CUPS <=1.3.9 is unable to list jobs on a CUPS 1.4
  server
  
  DEVELOPMENT: Karmic and Lucid side-stepped this bug by upgrading to CUPS
  1.4 clients. CUPS upstream fixed this in 1.3.10, and the attached
  patches backport that fix.

  for Jaunty
  
  INSTRUCTIONS: Reproduce by running `lpstat -h <server> -o <queue>`
  against a CUPS 1.4 queue.
  
  REGRESSION: I think regression is unlikely. The patches only add another
  option to lpstat requests - the patch is from upstream, no code is
  removed, and empirically the patch works.
  
  ===
  
  CUPS versions before 1.3.10 failed to include a printer-uri attribute in
  IPP_GET_JOBS requests issued by lpstat.
  
  Against servers running CUPS 1.4, this causes an error when you try to
  use lpstat to retrieve jobs:
  
    dr-wily:~ broder$ lpstat -h get-print.mit.edu -o ajax
    lpstat: No printer-uri in request!
  
  This can be fixed by backporting a patch from upstream (parts of r8146
  in http://svn.easysw.com/public/cups/branches/branch-1.3) - apparently
  the printer-uri value can be bogus, so long as it's there.
