** Description changed:

  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.

  [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.
