No. No matter where i map the key (and xev reports that symbol correctly) KKeySequenceWidget detects it wrongly as "Launch (1)" here (so i can confirm the bug).

It's probably related to keyboard driver (ie. evdev) since this:

setxkbmap -layout de -model microsofccurve2k -option terminate:ctrl_alt_bksp,ctrl:nocaps -variant deadgraveacute -rules xorg -keycodes evdev

leading to:

xkb_keymap {
        xkb_keycodes  { include "xfree86+aliases(qwertz)"       };
        xkb_types     { include "complete"      };
        xkb_compat    { include "complete"      };
        xkb_symbols   { include "pc+de(deadgraveacute)+ctrl(nocaps)+terminate(ctrl_alt_bksp)"   };
        xkb_geometry  { include "pc(pc104)"     };
};

leaves the key undefined and KKeySequenceWidget will probably fetch the symbol from the kbmap - thus mapping it anywhere has no effect here.

Nevertheless, this patch is certainly wrong and just manipulates a symptom of a sublying bug and will thus most likely cause trouble on systems not affected by that actual bug which should be fixed instead.

PS/OT:
it's btw. stunning how many MS keyboards seem in use - while except of the logo, there's really nothing i could concern about mine =)
