Applet crashes when changing preferences

[Hai NGUYEN VAN]

The applet suddenly crashes when I save sensor preferences different to the default ones. To repeat the bug:
1. Add to GNOME Panel, "Hardware Sensors Monitor" applet
2. Right-click on it, open "Preferences" then hit "Sensors"
3. Tick or untick sensors (for now, no problem) then "Close"
4. Bang! GNOME Panel is now shouting ""Hardware Sensors Monitor" has quit unexpectedly"
5. I get sad

This bug occurs on
- Ubuntu 16.04 x64
- with GNOME Classic Flashback Session
- sensors-applet 3.0.0+git5-0.1ubuntu1
- gnome-panel 3.18.3-0ubuntu0.1
