Public bug reported:

chromium-browser 37.0.2062.94-0ubuntu1~pkg1065 on Lubuntu Utopic amd64
sometimes crashes on launch. This happens at least daily, but somewhat
less than half the time the browser is launched. Following the crash and
without deliberately relaunching the application, Chromium usually still
seems to work (but Chromium uses multiple processes, so that is not
surprising). This is on a laptop with Intel i915 onboard video.

When I launch Chromium, both in cases when a crash occurs and in cases
when there is no crash, the Chromium window remains undrawn for a while
(perhaps half a minute), showing whatever was last drawn behind it. This
is confusing because it looks like other windows or the desktop are in
the foreground and could be interacted with, when actually they are not
--however, that is not the bug I am reporting here. Rather, I mention it
in case it is related to the crash (since it looks like the crash may be
related to OpenGL rendering).

In case it's relevant, the output of "sudo lshw -C video" is:
