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

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;

array [
string "SIGNAL=NameOwnerChanged"

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
