I have just uploaded 1:1.0.1-1 to unstable.  Assuming you can reproduce
these crashes with that version, please report them upstream, see
http://nouveau.freedesktop.org/wiki/Bugs.

You can also try to obtain a backtrace after installing a few debug
packages: xserver-xorg-video-nouveau-dbg, xserver-xorg-core-dbg,
libdrm2-dbg, libc6-dbg.  Please refer to
http://pkg-xorg.alioth.debian.org/howto/use-gdb.html.

I presume you have libcairo2 held back at 1.10.x?  With 1.12.x the
driver seems to be broken for everyone: http://bugs.debian.org/666468.
