OK, yes, at least give them a warning. I think the better solution is to advice the user of the correct action (as described in the bug description) and let him/her decide.

This is a major regression from Ubuntu 12.04. This poses a huge data loss potential. The easy way to solve this is to follow 12.04's policy. The computer can not shutdown/restart from any session while there are any other session logged in regardless it is Administrator, Standard or Guest session. The hard way is to follow this proposed policy: (A) Guest session can not shutdown/restart while there are any sessions logged in regardless they are Standard or Administrator users. (B) Standard user can not shutdown/restart while there is an Administrator user or another Standard user logged in. (C) Standard user can shutdown/restart while there is a Guest session logged in. (D) Administrator user can shutdown/restart while there is a Standard or Guest session logged in. (E) Administrator user can not shutdown/restart while there is still another Administrator user logged in. 1- In case of (A), a Guest tries to shutdown/restart, a message should pop up telling the Guest that s/he can not shutdown/restart but the session can be logged off, and maybe give a reason for that. 2- In case of (B), a Standard user tries to shutdown/restart, a message should pop up telling the Standard user that s/he can not shutdown/restart but the session can be logged off, and maybe give a reason for that. 3- In case of (C), a Standard user tries to shutdown/restart, a message should pop up telling the Standard user that s/he can shutdown/restart but the Guest could lose their data if not saved on external storage such as a USB stick, and advice him/her to log off that session first then shutdown/restart. 4- In case of (D), an Administrator user tries to shutdown/restart, a message should pop up telling the Administrator user that s/he can shutdown/restart but other users could lose their data if not saved, and advice him/her to log off those sessions first then shutdown/restart. 5- In case of (E), an Administrator user tries to shutdown/restart, a message should pop up telling the Administrator user that s/he can not shutdown/restart but the session can be logged off, and maybe give a reason for that.
