Title:
  cups 2.0.2-1 100% cpu usage

Status in cups package in Ubuntu:
  Fix Released
Status in cups source package in Vivid:
  Fix Committed

Bug description:
  upgraded from xubuntu 14.10 to 15.04 and now it uses cups 2.x
  after every print cupsd starts using 100% cpu and don't close.
  have to kill it every time with "sudo pkill cupsd"
  printing still works fine

  [Impact]

  CUPS 2.0.x can suddenly take 100% CPU in certain situations, making
  the system slow and producing fan noise.

  [Test Case]

  After printing a job cupsd takes 100% CPU. This does not occur for all
  users, probably depends on queue type and on timing (computer/network
  speed).

  With the proposed package the problem does not occur any more.

  [Regression Potential]

  Very low. The patch is very simple.
