GSpice-CRITICAL error in usb-device-manager.c when running spicy
I'm using spice-gtk 0.37 on macOS 10.14.6 and have an external monitor plugged in over Thunderbolt 3 (USB-C):
$ spicy --spice-debug --gdk-debug=all --g-fatal-warnings

Trace/BPT trap: 5If I remove --g-fatal-warnings, the error still appears, but I can connect establish a connection with another machine.
Adding --spice-disable-usbredir does not remove the error.
Lastly, this error goes away when the external monitor is unplugged.
