Hey im having problems when i try to execute system-config-display in my fedora13 RC3

The message im gettin is:

Traceback (most recent call last):

  File "/usr/share/system-config-display/xconf.py", line 378, in <module>

    dialog = xConfigDialog.XConfigDialog(hardware_state, xconfig, videocard.VideoCardInfo())

  File "/usr/share/system-config-display/xConfigDialog.py", line 640, in __init__

    if len(self.xconfig.layout[0].adjacencies) > 1:

IndexError: index out-of-bounds

Any ideas why im having this issue?

Thanks
