Why am I getting an error related to the Behaviour Plugin?

Question

I am running JIRA 5.1.7 and have the Behaviour Plugin v. 0.5.3 installed. When I try to create an issue, I receive this error: Error creating issue: Cannot invoke method getValidators() on null object. After I disable the plugin, the error message goes away and I'm able to create issues again. The error only appears in one of my projects, I can't help the source or cause of this error.

Thoughts?

Also see https://studio.plugins.atlassian.com/browse/JBHV-168 . Does that apply here?

When you turn logging on is there anything in the logs?

Can you go to the behaviours admin page, do Edit (I think) for the bad one and paste here the xml that you see in the big text field.
