chromium-browser and Google Chrome do not run when logged into Ubuntu as a Guest

[Christopher Barrington-Leigh]

I've tried this on 15.04 and 15.10 on multiple machines. Supposedly an earlier similar bug for Chrome was fixed for 14.10.

I log in using Guest Login from the lightdm startup screen.

I launch chromium-browser or google-chrome.

Instead of a window appearing, the terminal says, after some seconds

Check failed: NamespaceUtils::DenySetgroups()

and then does nothing.
