Public bug reported:
Binary package hint: xserver-xorg-core
When I start certain applications (for instance blender, texmaker, a
plot using matplotlib) X crashes and I'm back at the login screen. This
is what I can extract from /var/log/Xorg.0.log.old

I googled for it a little and I found these two links of I guess the
same problem and a patch:
