Just taking a superficial look, the bug is still in the input event
stack, and happens in an area of the code that may be difficult to
patch.

There are some Ubuntu-authored patches in the input stack for utouch and
the touch framework which might be involved in some fashion here,
although it's hard for me to be certain just judging these crash dumps.

I've prepared a PPA that have the multitouch patches switched off for
you to test.  These will help isolate whether the bug is in the ubuntu
MT patches or might be something upstream.  Please install this PPA and
test it, and report here if you can or can't get it to crash after that:

If it still crashes, the next step would be for you to uninstall that
PPA (use ppa-purge) and then install xorg-edgers and try reproducing on
that.  If it *still* crashes, then the bug should be forwarded upstream
at that point.
