Title:
  Chrome causes segfault in i965_dri.so

Status in Chromium Browser:
  Unknown
Status in “mesa” package in Ubuntu:
  Confirmed
Status in Debian GNU/Linux:
  New

Bug description:
  Running chrome 38.0.2125.66-1 on Ubuntu 14.10, on Lenovo X230

  When I start a new instance of chrome, it cannot enable WebGL. I have
  reported that bug separately to chrome at
  https://code.google.com/p/chromium/issues/detail?id=416207

  I suspect the cause of the bug is in mesa, as dmesg contains evidence
  of a segfault:
