chromium-browser segfault at bbadbeef

[Felix Triebel]

I put apparmor profile for chromium-browser into enforce mode, now chromium browser doesn't open any websites. I see this in the logs:
kernel: [23419.489431] chromium-browse[10809]: segfault at bbadbeef ip b69667db sp bff953c0 error 6 in chromium-browser[b4b63000+2d48000]

Thank you for using Ubuntu and reporting a bug. I'm adding an apparmor task since it provides the chromium profile.

For the most part, this looks to be a duplicate of bug #692866. Felix, can you adjust /etc/apparmor.d/usr.bin.chromium-browser from having:
owner /dev/shm/org.chromium.* mrw,

To having:
owner /dev/shm/{,.}org.chromium.* mrw,

and then perform:
$ sudo apparmor_parser -r -T -W /etc/apparmor.d/usr.bin.chromium-browser

Please report back if this fixes the issue for you.

Hi Jamie, I followed your description and now it's working properly.
Thank you for the excellent support! Felix
