Hi

I did some benchmarking of my D-Bus code which uses signals. After short
time I noticed that printer applet is using lot of CPU and memory. I believe
monitor_session function is responsible for this as it receives *all*
signals on session bus. What is even more funny, it does exactly
*nothing* with all these signals. I do not understand reason of this
code, but please add at least some filtering so that this method is not
called for all signals on session bus.
