I am having a problem with the shutdown dialog box for Ubuntu 12.04. If I am logged in as any user and press shutdown, I see the box with the question 'Are you sure..." and its usual options. Shutting down when I am not logged in as a specific user, however, displayed only square boxes.
An image of this error can be found here:
I believe this error started a few weeks ago when i accidentally changed the group for my root system directory, so it might be a permission thing or an improperly assigned group lingering somewhere. The trouble is that I don't know where the text for this box is stored, and no idea where to begin checking.
Can any one point me in the right direction?
