I've gotten that before too - it seems to be random - sometimes the logout works, sometimes it doesn't. I think it has to do with logging in/out with both windows authentication and FBA on the same machine. It does seem to be a SharePoint bug though, not the the FBA Pack, so hopefully it will be corrected in a future SharePoint service pack.

I can confirm that this is a SharePoint-Bug only. It appears without FBA Pack installed in Mixed mode usually at the 2nd sign out action.
