Note: the touchpad tab appeared in the mouse settings after one of the last updates today, though the issue with xinput persists.

Maybe the additional information provided by
valgrind xinput list-props "AlpsPS/2 ALPS GlidePoint"
(see attachment) can be usefull. Valgrind can be found on http://valgrind.org/.

I've nominated this for intrepid because it's a serious issue leading to a crash, and the fix is both minimal and already upstream. The change just cleans up a #define issue introduced in an earlier version of this package.

This will also necessitate rebuilds of several packages, which will be done once this is accepted into the archive: gnome-control-center, libxi, x11proto-input, xf86-input-evtouch, xfree86-driver-synaptics, xorg-server, and xserver-xorg-input-evdev. Builds can be found at wgrant's ppa: https://edge.launchpad.net/~wgrant/+archive

These patches are in, and these packages are now accepted, and will be built soon. Marking as fix released.
