CiviCase and Activity: copy email sent to assignee contains edit link with assignee as contact

If I add an activity to a Case, a confirmation email is sent to the assignee(s). Very useful, the project I am working on now use this to send workload to their colleagues. In the email that the colleague receives there are 2 links: a link with view activity and a link with edit activity. These links use the assignee as a client ID, so if I update the case activity with the link, I automatically move the whole case to the assignee!!

(see forum post http://forum.civicrm.org/index.php/topic,20458.0.html)

The same applies to the standard Activity dashlet, where the edit-link does the same.
