Errors when duplicating

Hi,

When testing the plugin I’ve got several errors (when running in Debug mode) when duplicating a post.

User has user role “Administrator” on site where he’s duplicating FROM.
User has user role “Contributor” on site where he’s duplicating TO.

I left out the stack trace information to not clutter the list.

But these last two are probably because of the errors being thrown.
