I have the same problem with 2 screens with Sony Vaio (Ubuntu 11.10 32bit).
timo@vaio:~$ nvidia-settings -q screens
2 X Screens on vaio:0
[0] vaio:0.0 (GeForce GT 230M)
[1] vaio:0.1 (GeForce GT 230M)
The second screen has a white background. If I move mouse to the second screen right click the white background I will get a segfault.
timo@vaio:~$ dmesg|tail -3
