It's 'kbd-macro-redisplay', not 'kbd-macro-display'.  Indeed it conflicts 
with the keys that are supposed to be reserved for user bindings, but it 
is by far not the only one:

C-x C-k Q	kdb-macro-redisplay
C-x C-k b	kmacro-bind-to-key
C-x C-k e	edit-kbd-macro
C-x C-k l	kmacro-edit-lossage
C-x C-k n	kmacro-name-last-macro
C-x C-k q	kbd-macro-query
C-x C-k r	apply-macro-to-region-lines
C-x C-k s	kmacro-start-macro
C-x C-k x	kmacro-to-register
