The problem occurs if you close the project while your message handler, which you installed after loading the project, is still installed.</p> <p>It's still a bug and so I opened <a class="" href="http://jira.3s-software.com/browse/CDS-38767" rel="nofollow">CDS-38767</a> in our bug tracker.</p> <p>BR<br/> Martin</p></div>
