This is your first problem, you cannot use NVidia's libGL.so.1 with
Nouveau.  What does "update-alternatives --display glx" print?

And this is the second one, using the xorg libglx.so with NVidia's
libGL.so.1 causes the crash.  With NVidia's libglx.so you would "only"
be unable to run any OpenGL programs, but the X server shouldn't crash.

NVidia maintainers, shouldn't the glx-alternatives system prevent such a
combination?
