I just marked a few other bugs as duplicates of this. As I wrote in one of them, I see this in nvidia-settings 331.20 on my Thinkpad W510 (Nvidia Quadro FX 880M) on Xubuntu 12.10, using the xorg-edgers PPA, which brings in Linux 3.7.0.7-generic. I'm pretty sure I don't see this on Xubuntu 13.10, with the same version 331.20 of nvidia-settings, using the ubuntu-x-swat/x-updates PPA. Maybe this suggests the specific version of some pixbuf library is the culprit. User ssm suggests it's gtk2-engines-pixbuf (https://bugs.launchpad.net/ubuntu/+source/nvidia- settings/+bug/1268027/comments/21).
Here's what I get in Xubuntu 12.10 while running it in gdb and then hitting close: user@box:~$ gdb nvidia-settings GNU gdb (GDB) 7.5-ubuntu Copyright (C) 2012 Free Software Foundation, Inc.
