Description of problem:
When I clicked on the button with 9 dots (The button next to a magnifying glass), it hangs and crashed.

I had just tried to compile SDDM 0.12.0 on Fedora 22 as well, since it is not updated there. 

Meanwhile, I am not sure if this issue is releated or not:

I am not able to connect WiFi through GNOME interface as well regardless of security level and the GUI does not show changes when I tried to disable WiFi. (Even though it is possible to connect to a unsecured WiFi via command line 'nmcli device wifi connect SSID')

Version-Release number of selected component:
nautilus-3.16.2-2.fc22
