In that link I found gnome-settings-daemon-dbgsym_3.4.2-0ubuntu2_i386.ddeb so I did a sudo dpkg -i on it. Then did gdb gnome-settings-daemon run --debug
Created the problem. A whole lot on the console. I looked in http://bugs.launchpad.net/gdb-linaro/>... which seemed to me to be a whole lot of bugs people reported with "no instructions" on how to report. Everything says look in http://bugs.launchpad.net/gdb- linaro/>... which is just a google type list of bugs people found and no instructions on what to do. So I copied the console output it's 27015 characters long attached. "backtrace" got (gdb) backtrace #0 0xb2ae9f00 in gdk_device_manager_list_devices@plt () from /usr/lib/gnome-settings-daemon-3.0/libmouse.so #1 0xb2aecec5 in gsd_mouse_manager_idle_cb (manager=0x8130248) at gsd-mouse-manager.c:1124 #2 0xb786b570 in ??
