Title:
  [G72] nvidia binary driver (295.40 and 295.49) segmentation fault

Status in “nvidia-graphics-drivers” package in Ubuntu:
  Confirmed

Bug description:
  I get the following seg fault when trying to use nvidia binary driver
  version 295.49 (posted here:
  https://launchpad.net/~suraia/+archive/ppa/+build/3464331).  I get a
  similar seg fault when using the official nvidia-current package
  (295.40).  The "nouveau" driver works fine (after I purge nvidia
  binary packages).  My card is GeForce 7300 SE.  Unfortunately, apport
  doesn't seem to think there is a problem.  Here are the (hopefully)
  relevant portions of my Xorg log:
