Uploaded a new fixed package to raring-proposed. As soon as the package
gets approved it will be available for testing and a comment with
instructions will be posted here. Please test it and give us feedback as
your feedback is required to make the package an official update.

SRU Team: debdiff is attached.

** Description changed:

  for some reason cups-browsed seems to be crashing or such, since dmesg
  is filled with this:
  
  [  415.118360] init: cups-browsed main process (4603) terminated with status 1
  [  415.118431] init: cups-browsed main process ended, respawning
  [  415.143189] init: cups-browsed main process (4608) terminated with status 1
  [  415.143293] init: cups-browsed main process ended, respawning
  [  440.099075] init: cups-browsed main process (4610) terminated with status 1
  [  440.099151] init: cups-browsed main process ended, respawning
  [  440.122735] init: cups-browsed main process (4613) terminated with status 1
  [  440.122843] init: cups-browsed main process ended, respawning
  [  465.080779] init: cups-browsed main process (4615) terminated with status 1
  [  465.080880] init: cups-browsed main process ended, respawning
  [  465.104684] init: cups-browsed main process (4631) terminated with status 1
  [  465.104762] init: cups-browsed main process ended, respawning
  
  on current raring
+ 
+ [IMPACT]
+ 
+ The bog does not actually lead to a loss of functionality, as if cups-
+ browsed does not keep running (and gets restarted by Upstart) it has
+ actually nothing to do, either because avahi-daemon is not running and
+ so Bonjour broadcasts of other machines cannot get browsed or by bogus
+ configuration of cups-browsed, turning off all its functionality. The
+ only problem are annoying repeated log file entries caused by the
+ respawning.
+ 
+ [TESTCASE]
+ 
+ Stop avahi-daemon and cups-browsed:
+ 
+ sudo stop cups-browsed
+ sudo stop avahi-daemon
+ 
+ Now start only cups-browsed
+ 
+ sudo start cups-browsed
+ 
+ Observe the process number of cups-browsed repeatedly running:
+ 
+ ps auxwww | grep cups-browsed
+ 
+ Every 30 sec (every minute?) the process number changes, meaning that
+ cups-browsed got restarted.
+ 
+ With the proposed package cups-browsed gets only restarted three times.
+ If there are three failures in 4 minutesm, upstart gives up on cups-
+ browsed, avoiding the clutter in the log files.
+ 
+ [Regression Potential]
+ 
+ Practically none. In nearly every user configuration avahi-daemon is
+ correctly running and so cups-browsed starts up correctly. For the few
+ users not having avahi-daemon running there are also no functional
+ changes. No code changes in the proposed package.

  [IMPACT]

  The bog does not actually lead to a loss of functionality, as if cups-
  browsed does not keep running (and gets restarted by Upstart) it has
  actually nothing to do, either because avahi-daemon is not running and
  so Bonjour broadcasts of other machines cannot get browsed or by bogus
  configuration of cups-browsed, turning off all its functionality. The
  only problem are annoying repeated log file entries caused by the
  respawning.

  [TESTCASE]

  Stop avahi-daemon and cups-browsed:

  sudo stop cups-browsed
  sudo stop avahi-daemon

  Now start only cups-browsed

  sudo start cups-browsed

  Observe the process number of cups-browsed repeatedly running:

  ps auxwww | grep cups-browsed

  Every 30 sec (every minute?) the process number changes, meaning that
  cups-browsed got restarted.

  With the proposed package cups-browsed gets only restarted three
  times. If there are three failures in 4 minutesm, upstart gives up on
  cups-browsed, avoiding the clutter in the log files.

  [Regression Potential]

  Practically none. In nearly every user configuration avahi-daemon is
  correctly running and so cups-browsed starts up correctly. For the few
  users not having avahi-daemon running there are also no functional
  changes. No code changes in the proposed package.
