Terminator terminal "Watch for activity" not working

[sp113438 <sp113438@telfort.nl>]

Hi,

Terminator is a nice program.
But terminator's "Watch for activity" and "Watch for silence" do not
work. They show up in the menu.

I have fluxbox window manager on Debian Jessie amd64.

Any ideas? Is something missing perhaps?

I installed:

libnotify-bin
oython-notify2
oython3-notify2

Thanks,

SP
