Comment (by Presskopp):

 There is no direct way to determine if a theme is a parent theme. However,
 indirectly, if a theme is not active and {{{data.actions['delete']}}} is
 not set, it is most likely a parent theme (although this is not
 guaranteed). That's why the patch is working. In a perfect world we would
 have a {{{has_active_child_theme()}}} method,
