Title:
  screen unpredictably crashes

Status in byobu:
  Invalid
Status in “eglibc” package in Ubuntu:
  Confirmed
Status in “screen” package in Ubuntu:
  Incomplete

Bug description:
  Recently on a wide range of unconnected servers, I've been noticing
  byobu sessions crashing out, with the message "Error: Cannot find
  master process to attach to!" appearing on the console/shell. I have
  not yet noticed any unifying factors; this happens when logged on to
  the physical console as well as over ssh, while the screen is in use
  as well as when it has been idle for a long time.

  byobu 2.68-0ubuntu1.1 and screen 4.0.3-14ubuntu1 are in use in all the
  cases I've seen (i.e. current upgraded Ubuntu 10.04 servers)

  {{{
  $ screen -ls
  There is a screen on:
  	4384.pts-0.leela	(14/09/10 23:55:39)	(Dead ???)
  Remove dead screens with 'screen -wipe'.
  1 Socket in /var/run/screen/S-jim.
  }}}

  I have never noticed this behaviour before, and I've been using
  vanilla screen for a long time; recently I've been switching to byobu
  because I find the on-screen info bars to be useful. For this reason
  I'm listing this bug against byobu, but I cannot prove that.

  Suggestions for increasing debug visibility would be appreciated -- I
  don't want to have to run multi-day sessions under strace, but if
  that's what it takes I can do that on at least one server.
