Ok, so it seems it thinks the Editor is being displayed somewhere. Again, on Windows we've sometimes had the problem where it was 'located' off of the visible screen area. I know ways to try to fix that on Windows, but someone else will have to offer suggestions for your platform.
Does nothing happen with the 'Reset Default Window Layout' command at the bottom of that menu? that should doc the editor back into the main GUI window.
Attached is the menu as i see it in the Windows version.
