"Binary package hint: gnome-applets

Hmm. I dont know much about it. I tried to change my cpu freq with the applet-- then it crashed.

gnome-applets 2.25.91-0ubuntu1

It's not reproducible for me. The crash is actually in dbus-glib so I wonder whether it's a bug in dbus-glib or cpufreq-selector.

I can confirm this bug with gnome-applets 2.25.92. The crash only happens if I
don't have permission to change the cpu frequency. If I grant myself
permissions with polkit-gnome-authorization, the cpu frequency changes
correctly.

To get a more complete stacktrace, I rebuild gnome-applets and dbus-glib
without optimization. See attached stacktrace.

Then, running cpufreq-selector under gdb, it turned out the error messages set
in "values" in "cpufreq_selector_service_error_get_type" are not available
anymore in "gerror_domaincode_to_dbus_error_name". Using a static const for
"values" solved the problem, see attached patch.
