 I don't think this is the same as the error I have filed this ticket for,
 this sounds like you are seeing some kind of fatal PHP error where
 presumably the page isn't loading at all? That's not the error that this
 ticket is related to if so, I think you may have some other issue
 happening with your use of wp_editor.
