When trying to create an event, I get the following error in my logs:  
`on(:post_created) handler error : ActiveRecord::RecordInvalid : Validation failed: An event accepts only group names.`

Creating the event:

Topic after thread creation:

This happens to me, when I try to create an event via the “upcoming events” calendar, and also if I try it via normal topic creation.

I could not find anything about it, so I assume it’s a bug?  
Does anybody else have this problem?
