Seems like you need absolutely the navigatorExtraButtons attribute since this 
fix.

Workaround add a seperator :
<sjg:grid
  ...
  navigator="true"
  pager="true"
  toppager="true"
  navigatorCloneToTop="true"
  navigatorExtraButtons="{seperator: { title : 'seperator' }}"
  >

Thanks for your great plugin.
