Blank nodes created by nodeprofile

An interesting thing is occurring on my development site. basically a blank node (without a node type) is being created whenever a user visits his or her own profile.

I have not really found the complete source of the problem but I do know when I set the user to not be able to edit their own profile then it stops doing this.

Does anyone have ideas on the best way to find out how this is happening? I'm reluctant to set my site live like this as it could really grow the database out of control in no time.
Also, why would drupal even let nodes be created without a nodetype? That seems like a bug to me.
