xfdesktop segfault in g_str_hash()

Issue Description

I use a KVM to switch to a laptop, then back to the PC and am presented with a blank screen.

I run a short script to restore visibility, when a crash is recorded.

Steps to Reproduce Issue

I have a KVM.

1. Switch to the laptop (as5) connection.

2. Switch back to the PC (e7).

   Screen remains blank, system does not switch to the display that was restored.

3. I run (blindly) a script ('x') I created for this:

xrandr --display ":0" --output "HDMI-1" --mode 3840x2160

sleep 1

xrandr --display ":0" --output "HDMI1" --mode 3840x2160

sleep 1

Expected Behavior

I expect the PC display to show up when the monitor is connected.

Otherwise, I expect it to show after running my script 'x'.

I expect no crash when 'x' runs.

Additional Information

This problem (blank screen) also happens if I unplug then plug the (HDMI) monitor.

The name of the monitor depends of which X driver is used. I now use modesetting and the monitor is listed as HDMI-1.
