Comment 13 for bug 995885

@ckelly Only if you have the PPA build of gnome-settings-daemon installed, which is a few versions stale. In addition, killing gnome-settings-daemon has some unfortunate consequences of having any application that depends on it for configuration fall back to defaults, unless restarted as well (this is most noticeable in Nautilus).

An update to my recent comments: The bug in question affects *ONLY* key shortcuts set via the Settings->Keyboard->Shortcuts dialog; any shortcuts defined directly in CCSM (Commands page) or via Ubuntu Tweak (Admins->Shortcuts) work as intended even if they use Super as one of the keys. This can be used as an effective workaround, permanently.
