[Ubuntu 14.04.3] Mouse clicks not logged

Hello,
I’ve installed WhatPulse 2.6.3 on my Ubuntu 14.04.3 LTS laptop.
I’ve set up the permissions and made sure all dependencies are installed.
Logging key clicks works fine but mouse clicks doesn’t seem to be logged.

I’ve attached the output from the terminal if that’s of any help.

Thanks in advance!
