I upgrade all of X and its dependencies to the versions currently in
unstable, and downgraded libgl1-mesa-dri, with no change. I had also
rebuilt libgl1-mesa-dri without Gallium (to work around #613596) but
that doesn't work either.
Investigating further, it turns out that X actually starts if it's
started on its own (rather than via gnome-session). Starting xterm
etc. works OK, it's after gnome-session starts that everything blows
up. I started X under gdb and got the following backtrace when it
segfaulted after gnome-session started:
Program received signal SIGSEGV, Segmentation fault.

Is that any use to you? Should I take the bug upstream?
