Clarification: When a process dies, it becomes a zombie until its parent reaps
(wait/waitpid) it. If its parent dies without reaping it, the process gets
reparented to init, which has pid 1, which is in turn supposed to reap it. If
init doesn't reap the process (due to a bug in init itself), then it remains a
zombie child of init. So it's not that init can never have zombie children. It's
that init *should* never have zombie children for extended periods, because it's
init's job to reap these zombie children.

Unfortunately, this isn't very helpful -- that's a normal Banshee log. I need
the one when Banshee refuses to start in order to tell what's going on.

Title:
  Cannot restart banshee after crash

Status in “banshee” package in Ubuntu:
  Incomplete

Bug description:
  If banshee crashes the sound/audio system menu still shows it as
  available but nothing happens if I click on it. With ps I can see a
  defunct banshee process that cannot be removed. If I try to run
  banshee from the command line nothing happens. Restarting gdm and/or
  unity also has no effect. As far as I can tell there is now no way to
  start banshee short of rebooting which is annoying. Does anyone know
  how I can start banshee without closing everything down and rebooting?
  Perhaps there is some part of Ubuntu that controls the sound menu and
  I can restart that? I was hoping it was part of gdm or unity but
  restarting them didn't help.

  Description:	Ubuntu 13.04
  Release:	13.04
  but I have seen the same behaviour in 12.04
