Daniel,

Having experienced this bug in the past myself, I would be happy to
collect more profiling data. Unfortunately I'm running your pre-proposed
PPA at the moment for which it seems there are no debug symbols. I'll
downgrade back to the stock package and install debug symbols as soon as
I am able. I'm assuming the following packages will be sufficient
(correct me if I have missed anything),

libunity-dev-dbgsym libnux-2.0-0-dbgsym compiz-core-dbgsym compiz-gnome-
dbgsym compiz-plugins-dbgsym libgl1-mesa-dri-dbg libgl1-mesa-glx-dbg
libnux-2.0-0-dbgsym

and the appropriate kernel symbols (linux-image-3.2.0-23-generic-dbgsym
in my case).

If anyone is interested in trying this themselves, follow the
instructions at https://wiki.ubuntu.com/DebuggingProgramCrash, install
the above packages, and try collecting another profile with Daniel's
original instructions. Moreover, I don't think it should hurt to enable
callgraph profiling (-g).
