Bug description:
When unplugged from USB, I notice when running $ top that init, dbus-
daemon, mpdecision are constantly using in total ~10% CPU.
The steps I have performed to cause this:
1) Ensure the device is off
2) Plug a USB cable into the device and a computer with MTP support
3) Boot the device
4) Unlock the device, run the terminal and the command $ top
5) Wait until the CPU settles, then unplug the USB cable
6) Now notice that init, dbus-daemon, mpdecision start using ~10% CPU
This is the output from running dbus-monitor [0]
Note that when I plugged my device into a PC the CPU usage reduced
back to normal, but then when I unplugged it again it increased back
to ~10% again.
