Title:
  pulseaudio crashed with SIGABRT in pa_xmalloc()

Status in pulseaudio package in Ubuntu:
  Fix Released
Status in pulseaudio source package in Trusty:
  Confirmed

Bug description:
  1. Powered up laptop from a powered off state
  2. Logged in
  3. Was presented with "A system error has occurred"
  4. Later notice that "No PulseAudio daemon running, or not running as session daemon."

  I cannot control the volume, since no pulseaudio daemon is running
  $ pacmd does not work due to 4

  Trying to start pulseaudio gives me

  $ pulseaudio
  E: [pulseaudio] pid.c: Daemon already running.
  E: [pulseaudio] main.c: pa_pid_file_create() failed.

  Trying to kill it yields

  $ pulseaudio -k
  E: [pulseaudio] main.c: Failed to kill daemon: No such file or directory

  "I have no idea what I am doing":

  $ sudo pulseaudio -k
  [sudo] password for jonas:
  E: [pulseaudio] core-util.c: Home directory not accessible: Permission denied
  E: [pulseaudio] main.c: Failed to kill daemon: Success

  jonas@jonas-xps:~$ pulseaudio -k
  E: [pulseaudio] main.c: Failed to kill daemon: No such file or directory

  jonas@jonas-xps:~$ pulseaudio
  W: [pulseaudio] pid.c: Stale PID file, overwriting.
  E: [pulseaudio] module-device-restore.c: Failed to parse module arguments
  E: [pulseaudio] module.c: Failed to load module "module-device-restore" (argument: "restore_device=false"): initialization failed.
  E: [pulseaudio] main.c: Module load failed.
  E: [pulseaudio] main.c: Failed to initialize daemon.
  E: [pulseaudio] xmalloc.c: Assertion 'size > 0' failed at pulse/xmalloc.c:62, function pa_xmalloc(). Aborting.
  Aborted (core dumped)

  Happens due to 
  load-module module-device-restore restore_device=false
