Good night, i want to use indicator-cpufreq, but it is not possible, i think that when i start it, i get an infinite loop and it doesnt start

I think i am doing it well, here you have a snapshoot when i try to start it

But 6 or 7 minutes later, it continues at the same point, i have to stop it with Ctrl-c, and shows that:

It says:" Traceback (most recent call last): File "/usr/bin/indicator-cpufreq", line 82, in gtk.main() KeyboardInterrupt"

I do not have idea of what do for fix that, i hope you can help me to do that

Thanks for your time and sorry about my english
