nvidia-settings crashed with SIGSEGV in free()

[komputes]

Binary package hint: nvidia-settings

I have two monitors one VGA and one DVI. I am trying to make an extended desktop and am experiencing many issues.

Just installed Ubuntu 9.10 on a computer using the following VGA controller:

01:00.0 VGA compatible controller [0300]: nVidia Corporation NV34 [GeForce FX 5200] [10de:0322] (rev a1)
 Kernel driver in use: nvidia
 Kernel modules: nvidia, nvidiafb

There are many issues I have experienced:

- when trying to "Save to X Configuration File" nvidia-settings crashed with error: Failed to parse existing X config file '/etc/X11/xorg.conf'!
-Fullscreening (maximized) applications take up the whole desktop. Fullscreening in totem, displays the movie on both screens and crashes totem. How can I avoid this?
-Windows that pop up end up in the middle of the desktop meaning the dialog is shared on both screen (no concept of primary monitor)
-Artefacts are seen when moving windows around when compiz is run
-Since the resolutions do no match on the Y-axis (vertical) gnome panel runs into invisivle space, not displaying half of the icons on the right of the second screen (right).

See terminal.log first for errors concerning ~/.nvidia-settings-rc

I erased .nvidia-settings-rc to avoid the error and got the following when trying to create two X sessions (one for each screen) and trying to save to xorg.conf

mike@TheXeons:~$ sudo rm .nvidia-settings-rc
mike@TheXeons:~$ sudo nvidia-settings

VALIDATION ERROR: Data incomplete in file /etc/X11/xorg.conf.
Undefined Device "(null)" referenced by Screen "Default Screen".

Segmentation fault (core dumped)

[komputes (komputes)]

What I did to somewhat fix the situation:

sudo rm ~/.nvidia-settings-rc
sudo rm /etc/X11/xorg.conf
sudo nvidia-settings
# In the nvidia settings, Configure the two monitors to be 2 Seperate X Screen and enable Xinerama
# Saved to /etc/X11/xorg.conf (had to define file path)
# Edited xorg.conf to the attached, redefining define monitor 0 and 1 and switched the positioning from RightOf to LeftOf (personal preferences)

What issues exist in this configuration:
-Compiz cannot be enable. I get the following error when trying to set the appearance to "Extra":

The Composite extension is not available

All of the compiz parts of this report are already reported (bug 277801 for example).
