Can you attach the error that you get when running nvidia-settings from the command line, please? Also, the output of gdb would be welcome.

Does the attached package solve the problem?

It does not seem to:

1) Does that happen when you save and exit or when you exit without saving?
2) What happens if you do "sudo apt-get --purge remove nvidia-settings" and install the deb package?
3) Please use the package from precise-proposed and collect a backtrace using apport. You can do so by starting apport with "sudo service apport start force_start=1" and triggering the error again.

4) Does it help if you remove ~/.nvidia-settings* and then you start nvidia-settings?

This happens when I exit without saving.

Same thing.

4) Does it help if you remove ~/.nvidia-settings* and then you start
nvidia-settings?

No, still crashes the same.

I think that has been done.

if you do what I asked in 3), I'll also get the debugging symbols in the backtrace which, in turn, will help me understand the problem better.

I already am using the package from precise-proposed:

$ apt-cache policy nvidia-settings

I was referring to catching a full backtrace using apport so that we also get the debugging symbols

Please start apport with "sudo service apport start force_start=1" and trigger the error again.

I did run the command already, all it does is: "start: Job is already
running: apport", nothing else happens when I crash it. At most, it asks if
the error should be reported and uploaded - I say continue, and nothing
else after that.

weird, that should have sent the errors to https://errors.ubuntu.com.

Here's how to enable the crash interception component, please give it a try:
https://wiki.ubuntu.com/Apport#Ubuntu_12.04_and_later

Nothing happend:

vadi@gooseberry:~$ sudo nano /etc/apport/crashdb.conf
[sudo] password for vadi:
vadi@gooseberry:~$ nvidia-settings ^C
vadi@gooseberry:~$ cat /etc/apport/crashdb.conf | grep problem_types
        # 'problem_types': ['Bug', 'Package'],
vadi@gooseberry:~$ nvidia-settings

** (nvidia-settings:18810): WARNING **: PRIME: Failed to execute child
process "/usr/bin/prime-supported" (No such file or directory)
** Message: PRIME: is it supported? no
Segmentation fault (core dumped)
vadi@gooseberry:~$ ls /var/crash/
vadi@gooseberry:~$

So I purged apport and apport-gtk to remove and config files and reset any
possible "don't show me the crash again" settings, reinstalled them both,
but it still did not come up.

I think I know what's going on.

Please replace the following line:

# 'problem_types': ['Bug', 'Package'],

with the following:

# 'problem_types': ['Bug', 'Package', 'Crash'],

You can test that apport is running by causing a crash:
sh -c 'kill -SEGV $$'

I had set apport to ignore the file and I found the setting
in ~/.apport-ignore.xml. It would seem purging did not remove that file as
I expected.

Having removed an entry in there, I got the dialog to report the crash,
which I did at:
https://bugs.launchpad.net/ubuntu/+source/nvidia-settings/+bug/1270490

that page says:

This page does not exist, or you may not have permission to see it.

If you have been to this page before, it is possible it has been removed.

The page is still classified: "The information on this page is private.".

I can access the page now

bug #1270490 looks like bug #1226968 which wouldn't make it a regression in precise-proposed

on amd64 I try to reinstall gtk2-engines-pixbuf for libpixbufloader-xpm.so,
but failed still get segfault, then
got package gtk2-engines-pixbuf_2.24.10-0ubuntu6_amd64.deb , and
dpkg -i gtk2-engines-pixbuf_2.24.10-0ubuntu6_amd64.deb
check with apt-get install -f, and was ok.

I just marked this as a duplicate of Bug #1214508. Alberto Milone, could you assign yourself to that bug?

Getting some really odd hack jobs on my computer. Please test and get back to me.

Latest was this Bug from Nividia
