Hi Selene,

I've studied this a bit more and come up with a plan.

1.  I notice in your Dependencies.txt that it lists you as having -evdev
u12 installed, but there is an -evdev u12.1 available with a fix to a
bug not dissimilar to this one (LP #774978).  The backtrace in that case
is different, but it was a very common bug with very similar symptoms,
so perhaps yours is some variant of it.

Possibly you already natty-updates enabled and have that fixed version
installed now , but please doublecheck and if not pull it in and test
it.

  apt-cache policy xserver-xorg-input-synaptics


2.  If #1 doesn't do it, comment #13's findings might be interesting to explore.  One of the main differences between us and debian are the Xi2 multitouch patches.  I've prepared a set of packages for you to test which have these patches disabled.  Please install this whole PPA and try reproducing the crash:

  https://launchpad.net/~bryce/+archive/melon


3.  The backtrace in this case is not telling us exactly what is going on.  It's like finding your car in the lake - the lake didn't cause the crash, it's just what ruined all your upholstery.  So, to try and get a bit better details, I've prepared a debug version of xserver.  Disable and uninstall the melon PPA from #2, and install this one instead:

  https://launchpad.net/~bryce/+archive/x-debug

Then, reproduce the crash and collect another backtrace (or collect
several if you notice the backtrace varies from crash to crash).  Then
uninstall the PPA (ppa-purge can be useful here).


4.  Finally, if none of the other options work, please install the xorg-edgers PPA and verify the crash still occurs there.  If it does, I can forward the bug upstream.  Again, ppa-purge can be used to restore your system back to non-xorg-edgers when you're done.
