chromium-browser crashed with SIGSEGV in gpu::gles2::GLES2DecoderImpl::Initialize()

[Eliah Kagan]

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:
