SUMMARY
    Plasmashell crashes when I unmount a USB by using "Safely Remove" option from System Tray applet.

STEPS TO REPRODUCE
1.  Insert a USB and mount it.
2.  Unmount the mounted USB by clicking on "Safely Remove" option in System Tray applet.
3.  See the plasmashell crash and restart itself.

OBSERVED RESULT
    When I unmount a mounted USB, the systray applet shows that the USB has been safely removed and then crashes and replaces itself. Plasmashell doesnt crash after unmounting the USB sometimes, so by doing it repeatedly, this issue would appear.

EXPECTED RESULT
    Unmounting a USB shouldn't result in a plasmashell crash.
