Looks like DesktopAppInfo.get_icon() is returning NULL when called by MediaPlayer's "icon" property getter, and we're passing that NULL into g_icon_serialize().

Fix committed into lp:indicator-sound at revision 398, scheduled for release in indicator-sound, milestone Unknown

Fix committed into lp:indicator-sound/13.10 at revision None, scheduled for release in indicator-sound, milestone 0.5.6

This bug was fixed in the package indicator-sound - 12.10.2+14.04.20131029.1-0ubuntu1

---------------
indicator-sound (12.10.2+14.04.20131029.1-0ubuntu1) trusty; urgency=low

  [ Dmitrijs Ledkovs ]
  * Define "ubiquity" indicator profile, reusing the greeter object. (LP:
    #1241539)

  [ Charles Kerr ]
  * When we can't connect to pulse, wait a moment before retrying. (LP:
    #1244010)
  * In Service's volume_changed() function, explicitly instantiate the
    GVariant to avoid leaking it. See the description in bug #1244468
    for before & after C code and more information. (LP: #1244468)
  * Test that MediaPlayer's icon property isn't NULL before we serialize
    it. (LP: #1229612)

  [ Sebastien Bacher ]
  * Don't special case Unity sessions, that's not needed since gnome-
    control-center is doing the right thing, the session name used was
    also wrong and couldn't work (lp: #1239545). (LP: #1239545)

  [ Lars Uebernickel ]
  * Only display running players in the phone's sound menu The design
    says to only display the _one_ running player. This will have that
    effect, as there's only one player allowed to run at a time on the
    phone.
  * VolumeControl: don't pass vala closures into libpulse Libpulse's
    vala bindings don't specify that callbacks passed into some of its
    functions (e.g., get_server_info) can be called after the function
    returns. Vala thus frees closure data after these functions return.
    This can't easily be fixed in the bindings, because libpulse doesn't
    provide variants of these functions with destroy_notifies. This
    patch works around this problem by only passing non-closure
    functions into libpulse. (LP: #1244386)
  * Depend on vala 0.20 and use its GIcon.serialize().

  [ Ted Gould ]
  * Adding a phone_greeter profile.

  [ Ubuntu daily release ]
  * Automatic snapshot from revision 399
