Gnome Backend Init error

[Alex Mandel]

I tried to add cpufreq to my top menu bar in gnome, but it never showed 
up, no icon available and the correct components were not installed.
Now every time I start gnome I get a backend init error.

How do I manually remove the button I can't see from the menu?
