Title:
  pulseaudio crashed with SIGSEGV in module_jack_sink_LTX_pa__init()

Status in “pulseaudio” package in Ubuntu:
  Fix Committed

Bug description:
  Binary package hint: pulseaudio

  For some strange reason, I don't know why PulseAudio crashed when I
  open up ZynAddSubFX, but when I close it, start PulseAudio, and open
  ZynAddSubFX, it seems PulseAudio does not crash.

  This is what I have for PulseAudio/JACK in /etc/pulse/jack.pa:

  #!/usr/bin/pulseaudio -nF
  #
  load-module module-jack-sink
  load-module module-jack-source

  load-module module-native-protocol-unix
  load-module module-volume-restore
  load-module module-default-device-restore
  load-module module-rescue-streams
  load-module module-suspend-on-idle
  .ifexists module-gconf.so
  .nofail
  load-module module-gconf
  .fail
  .endif
  .ifexists module-x11-publish.so
  .nofail
  load-module module-x11-publish
  .fail
  .endif

  This is how I setup my ALSA-PulseAudio bridge:

  pcm.pulse
  {
      type pulse
  }
  ctl.pulse
  {
      type pulse
  }
  pcm.!default
  {
      type pulse
  }
  ctl.!default
  {
      type pulse
  }

  I will have to restart my netbook to see if the crash occurs again.
