Comment 6 for bug 685215

Of course, it would be slightly better to fix users-admin not working as root, rather than showing an error message, just in case some very special distributions or users need this. But I'd accept a patch showing a dialog too if it's well written... I don't think translators will mind - if you think it's worth your time, they will take a few seconds to translate it.

But for the message, it wouldn't be specific to users-admin, rather common to all tools, so something like "This program shouldn't be run as root. Please run it as a normal user and let it acquire privileges when necessary." would be better.
