Title:
  Xorg crashes in drm_intel_bo_is_reusable() from intel_set_pixmap_bo()

Status in Compiz:
  Invalid
Status in X.org xf86-video-intel:
  Unknown
Status in “libdrm” package in Ubuntu:
  New
Status in “xserver-xorg-video-intel” package in Ubuntu:
  New

Bug description:
  re-redirecting an unredirected OpenGL window sometimes kills the X
  server.

  Test case:
    1. Enable "Unredirect Fullscreen Windows" in CCSM > Composite.
    2. Start an OpenGL game, or video with: mplayer -vo gl ...
    3. Trigger scale (Shift+Alt+Up) or the window menu (Alt+Space)
  If it doesn't crash, then repeat.

  Expected: Either windows scale or the window menu appears
  Observed: Sometimes, just sometimes, X crashes and I get sent back to the login screen.

  Program received signal SIGSEGV, Segmentation fault.
