I installed KDE4 from the current svn trunk.

My problem is that I cannot define shortcuts that use the Super_L (aka Windows) key in "System Settings -> Keyboard & Mouse -> Keyboard Shortcuts". When I try to define a shortcut and press the windows key, the button displays only some boxes.  (Those boxes you get when the font you use has no glyph for this character.)

If I type for example "Win+E" I get "°°°^, E" displayed in the button instead, where ° is a box that seems to be some subscirpt (it reaches below the button) and ^ is a box in normal height.

This is what I get with xev when I press and release the windows key.

KeyPress event, serial 31, synthetic NO, window 0x1a00001,
    root 0x1a6, subw 0x0, time 49421672, (-617,460), root:(299,485),
    state 0x0, keycode 115 (keysym 0xffeb, Super_L), same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

KeyRelease event, serial 31, synthetic NO, window 0x1a00001,
    root 0x1a6, subw 0x0, time 49421779, (-617,460), root:(299,485),
    state 0x40, keycode 115 (keysym 0xffeb, Super_L), same_screen YES,
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

Looks ok, I'd say.

Because I'm an emacs addict and as such cannot have my desktop "steal" any Alt- and Ctrl-shortcuts, this is really a showstopper for me.

I try using KDE4 for a week now and svn-updated and recompiled daily, but this bug was and is always there.
