Will try that if all else fails or things get too annoying.

I have seen a few more crashes:

but have not been able to get a core dump for some reason.
ulimit -c says unlimited but no core file could be found.

I will now try to attach gdb to it to try to catch a crash.

I still don't know how to trigger a crash which makes this a
wait-and-see game for now. The good news is that gnome-session doesn't
seem to lobotomise itself that often and gnome-settings-daemon seems to
be restarted. Now the theme just goes back to basic for a few seconds
and then comes back.

Thanks
