These two crashes seem unrelated.  Aaron, I suggest you file a new bug
against the libpixman-1-0 package, including your X log.
If you're able to get a stacktrace from gdb when X crashes, that would
be very helpful (make sure you have libpixman-1-0-dbg,
xserver-xorg-core-dbg and xserver-xorg-video-intel-dbg installed, and
run gdb from another machine using ssh).

Cheers,
Julien
