Please add :package-version and :safe keywords to the definition.

Also, type does not match the default value. You probably mean

(choice
 (string :tag "Header")
 (const :tag "No header" nil))

Maybe:

  (insert (propertize org-agenda-clock-report-header 'face 'org-agenda-structure))

Could you send an updated patch?
