Default Xinerama with 2 video cards, 3 monitors

I currently have two identical 1600x1200 LCDs connected to a NVIDIA 7600 GS configured to use TwinView on Linux (I'm using X11 1.7.7 and NVIDIA driver 256.44); I'm using xfce 4.6.2 as my desktop environment. I've been trying to configure a third LCD (with 1920x1080 resolution) I connected to a GTX 260 I added to the system. I can start X11 successfully on all 3 screens without Xinerama or TwinView enabled; however, when I turn on Xinerama and attempt to start X11, I see the following errors in my ~/.xsession-errors file:

/etc/X11/Xsession: line 40: 4938 Segmentation fault xsetroot -cursor_name watch
/etc/X11/Xsession: line 54: 4939 Segmentation fault xrdb -nocpp -merge $sysresources
/etc/X11/Xsession: line 62: 4940 Segmentation fault xrdb -merge $userresources2
Xlib: extension "RANDR" missing on display ":0.0".

Gdk-ERROR **: unable to find a usable depth
aborting...
/etc/X11/xinit.d/nvidia-settings.xinit: line 9: 5016 Aborted
/usr/bin/nvidia-settings --load-config-only
Running update-menus...
localhost being added to access control list
Xlib: extension "RANDR" missing on display ":0.0".

Gdk-ERROR **: unable to find a usable depth
aborting...
menu generation finished

Does anyone have any idea why this could be happening?

Sorry, this is probably a bug that we recently discovered. A fix will be available in a future release.

I just tried driver version 260.19.12 and the bug appears to have been fixed.
