xfce4-display-settings crashes with multiple monitors

Running xfce display settings either via the settings manager in xubuntu or from the command line does crashes out with the error dialogue:

Unable to start the XFCE Display Settings

with no further information echoed to the command line. This started after trying to get dual monitors working using the NVidia X Server Settings application to detect the second monitor and write the xorg.conf, as XFCE display settings refused to recognise the extra monitor. NVidia X Server Settings produced the following:

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 280.13  (buildd@rothera)  Thu Aug 11 17:28:49 UTC 2011

The second monitor now works, the mouse cursor moves between the monitors correctly, but right-click menus are now broken, the second monitor displays a copy of the desktop icons without wallpapers, and I can't move windows to the second monitor (nor launch them there).

Has anyone experienced this before?

Thanks!
