workflow notification problem

I'm experiencing a problem with the kaleo workflow engine. Here is my workflow source :

<?xml version="1.0"?>

The problem comes from the second notification in the review task because of the add of the user-notification notification-type. I first try the onExit execution-type (which was the suited type) but i got a NullPointerException (for the user-notification).
When i try the onEntry execution-type, i do have a user-notification but this notification contains the review process which means that the user (which is not a reviewer) may assign the task to itself and then approve it's own content...

By the way, the subject of the notification email shouldn't be the name of the notification in the workflow ? Because the notification email that i receive doesn't contain any subject...
