Inline Form Errors conflict

I've got a minor conflict with IFE module - it's removing the $SESSION['messages']['error'] key and then condition errors is getting the messages (after detecting form errors) and trying to loop over them.

I've checked this against latest dev versions. I think there should just be a wrapper to check that the 'error' section is set. there might be a more correct solution... i tried getting IFE to clear form errors so that condition_fields didn't think there were any errors to check.
