Title: If the ItemMeta is null then don't mess with it.

This is untested but I believe it is what is causing your NPE's. The line I added makes sure that the ItemMeta isn't null, but if it is null then we don't mess with the event. Might want to test this out to make sure it isn't throwing the errors any more as I haven't tested it..just suggesting what it could be.
