Based on the xorg log this looks like some kind cursor/mouse/input
related bug. Its probably a good idea to try either the xorg
mailinglist or simply file a bug. You should do something like:

If you ask on the mailinglist i would put this ("BUG: triggered 'if
(!dev->valuator || dev->valuator->numAxes < 2)' BUG: getevents.c:845
in scale_to_desktop()") in the title, this hopefully triggers whoevers
knows what the problem could be to look at it.
