Hey Floris, this is an old bug.
Could you please still reproduce this issue with newer gnome-shell version like 3.4.2-7+deb7u1 or 3.8.4-5+b1 ? the new path from dconf-editor is: org.gnome.shell.overrides.button.layout here with 3.8.4-5+b1 if I remove the ":" on that field it just move the close button to left for instance. cheers, althaser
