I can confirm this also occurs for me with a fresh and fully updated Lubuntu 13.10, but just for hibernate. Manually executing pm-hibernate from a terminal works fine - executing it from the logout menu blanks the screen briefly, returns to the lock screen and, upon logging back in, displays the 'operation not permitted' error at the bottom of the logout dialog.
