Another user experienced a similar problem: From GNOME Control Center, I tried opening the Power panel. The application froze for a while, then it eventually crashed. Running it in the terminal, I got this at the moment of the crash: (gnome-control-center:544): libupower-glib-WARNING **: up_client_get_devices failed: Timeout was reached Segmentation fault (core dumped) reporter: libreport-2.6.0 backtrace_rating: 4 cmdline: gnome-control-center crash_function: set_ac_battery_ui_mode executable: /usr/bin/gnome-control-center global_pid: 398 kernel: 4.0.5-300.fc22.x86_64 package: control-center-3.16.2-1.fc22 reason: gnome-control-center killed by SIGSEGV runlevel: N 5 type: CCpp uid: 1000
