Bug description:
  After upgrading network-manager to 1.1.93-0ubuntu1~vivid1, dbus-
  monitor shows spam with NameOwnerChanged signals - there's no crash
  files or anything, but the top of top looks like so:

    PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND
   2921 phablet   20   0 1164048 277924   7444 S  34,9 28,3   4:18.54 ubuntu-push-cli
    847 message+  20   0    6412   2444    832 R  32,9  0,2   3:43.92 dbus-daemon
   2255 phablet   20   0    7080   2172   1156 R  22,2  0,2   2:40.95 upstart

  dbus-monitor shows hundreds of events like so:

  signal time=1462098650.817539 sender=:1.0 -> destination=(null destination) serial=11224 path=/com/ubuntu/Upstart; interface=com.ubuntu.Upstart0_6; member=EventEmitted
     string "dbus"
     array [
        string "SIGNAL=NameOwnerChanged"
        string "BUS=session"
        string "INTERFACE=org.freedesktop.DBus"
        string "OBJPATH=/org/freedesktop/DBus"
        string "SENDER=org.freedesktop.DBus"
        string "ARG0=:1.167"
        string "ARG1="
        string "ARG2=:1.167"
     ]

  3s of dbus-monitor:

  $ time dbus-monitor > dbus.log
  ^C
  real    0m2.719s

  Shows 226 signals - so it's just under 100 signals a second:

  $ grep -c NameOwnerChanged dbus.log
  226
