Hi Adam. I'm surprised you didn't get an apport window to report it.
I'm interested in that part, if you have time, after all this is
over.
I did get an apport window, but I think the report failed to submit
since it would need to use a web browser to do that, and my default
browser (Epiphany) won't run due to this very crash!
I'm not sure I will be able to help with the "low graphics" part of
your complaint. Chromium shouldn't crash, though, regardless.
What version of chromium-browser is that? Will you please install
the "chromium-browser-dbg" package and run "chromium-browser --debug"
from a terminal? "r" to run. Paste "bt full" on crash.
I have chromium-browser 31.0.1650.63-0ubuntu1~20131204.1. So OK - I've
included the Chromium stack trace below. It looks like it's dying in
PulseAudio code. Oddly, if I run Epiphany in gdb then the stack trace
there looks completely different - Epiphany seems to be crashing
somewhere in WebKit. I'll include that stack trace below as well.
All this behavior is odd enough that yesterday I did a clean install of
14.04 from the latest daily image. But these crashes are still
occurring. I'd be curious to know if anyone else is seeing similar
trouble.
