The edit short-menu (in recent-searches dropdown) is nok.

It concatenates the current page name with the new pagename you've entered in the input text field.

Fix needed to SearchBox.jsp, specifying an empty page parameter :

   <a href="javascript://nop/" 
   onclick="SearchBox.navigation( '<wiki:Link format="url" page="" context="edit"/>','<wiki:Variable var='pagename' />' );return false;"
     title="Edit the selected page">edit</a> 

Thanks! Fixed in 2.4.3...
