XF 1.2 Strange intermittant permission error since 1.2

[fist34]

After upgrading to 1.2 I am intermittently getting the following error:

"You do not have permission to view this page or perform this action."

This is on my own admin account. It happens if I have been idle for a while so I guess it has to do with not being logged in. But I am getting this error on pages that are public, and, I log in with the option to stay logged in.

If I simply reload the page, the error goes away.

Do you have any add-ons installed?

Try disabling them and testing again.

It may be your CSRF (security) token expiring, which is regenerated on page load. Do you receive this doing an AJAX action (fetching alerts, saving a draft, etc.)?

Only Resource Manager, and it's a vital part of the forum.

I receive it just when I try to view a new page after not having used it for a while. I also get it if I try to log in after I have been logged out for a while. But I can't make it fail just by logging out and back in.
