Comment 17 for bug 805894

I can confirm that this bug happens in Ubuntu 11.10 if a Western Digital My Book (1 Tb mirroring) is connected through USB.
Disconnecting the WD results in a gnome-settings-daemon that doesn't crash.

This bug can be temporarily fixed by executing the following script as startup item in "Startup Applications" :

#!/bin/bash
xinput --set-prop "Western Digital My Book" "Device Enabled" 0
nohup gnome-settings-daemon & > /dev/null
killall nautilus
nohup nautilus -n & > /dev/null

This is the part in my /var/log/udev that shows that udev is seeing the USB HDD as a hid device.
I'm no udev expert, so I might be wrong about this.
