First of all I apologize for my possible bad english.

Well I have the same problem and found some more information :

Description: Ubuntu 12:04:1 LTS
Release: 12.04
x86_64

When I look at my syslog file I found this line :

Aug 27 16:47:53 kernel: type=1400 audit(1346078873.846:2503): apparmor="DENIED" operation="open" parent=1 profile="/usr/lib/lightdm/lightdm/lightdm-guest-session-wrapper" name="/proc/3574/oom_score_adj" pid=3574 comm="chromium-browse" requested_mask="wc" denied_mask="wc" fsuid=119 ouid=119
Aug 27 16:47:53 kernel: type=1400 audit(1346078873.846:2504): apparmor="DENIED" operation="capable" parent=3574 profile="/usr/lib/lightdm/lightdm/lightdm-guest-session-wrapper" pid=3578 comm="chromium-browse" capability=21  capname="sys_admin"

Also when launching chromiun in a shell I get this error :
Failed to move to new PID namespace: Operation not permitted


When I try to fix this error by creating a child profile in apparmor I'm now with this error :
Failed to determine real pocess id of new "init" process

the new syslog :


Aug 27 23:03:29 kernel: [206330.553415] type=1400 audit(1346101409.730:6150): apparmor="DENIED" operation="open" parent=9565 profile="/usr/lib/lightdm/lightdm/lightdm-guest-session-wrapper//chromium" name="/proc/9854/oom_score_adj" pid=9854 comm="chromium-browse" requested_mask="wc" denied_mask="wc" fsuid=119 ouid=119
Aug 27 23:03:29 kernel: [206330.556458] type=1400 audit(1346101409.734:6151): apparmor="DENIED" operation="open" parent=1 profile="/usr/lib/lightdm/lightdm/lightdm-guest-session-wrapper//chromium" name="/proc/9859/status" pid=9859 comm="chromium-browse" requested_mask="r" denied_mask="r" fsuid=119 ouid=0

I'm still working around but due to the lack of information on apparmor profile it's a little hard.
In attachment the profile I last use as an attempt to fix the bug.
