Status in Chromium Browser:
  Unknown
Status in “chromium-browser” package in Ubuntu:

Bug description:
  chromium-browser crashes very often on my system, leaving the following in dmesg (excerpt):
  [69260.837159] chromium-browse[21110] general protection ip:b55fdfe9 sp:bf9caab0 error:0 in chromium-browser[b3206000+456a000]

  I usually get an application-crashed information in the systray, but
  due to apport bug #1058376, no crash report ever gets send to
  Launchpad.

  This does not seem to depend on the website being looked at. It
  appears randomly and is not reproducible when watching the same
  website again. It seems to happen only when leaving one page / loading
  another, but never when the page is already loaded. Sometimes Chromium
  does not crash, but freezes instead and has to be killed.

  It happens only since a few weeks (maybe 1-2 months at max), so it
  could be caused by an update to some library. Chromium was also
  updated during that timeframe: chromium-browser:i386
  (18.0.1025.168~r134367-0ubuntu0.12.04.1,
  20.0.1132.47~r144678-0ubuntu0.12.04.1), from /var/log/apt/history.log.
  I downgraded to a version archived on Launchpad [1], which does not
  show the bug.
