Thank you Luis. I did also put a minimal case reflecting my (weak) 
design. The only difference with yours is that the loop of connection is 
less obvious, because it happens through pointers to base classes, 
because we tried to let some classes know just what they need to know 
about some others. But I understand the problem now and will have a 
close look to the design and in last resort use the WeakPointer. Thank 
you very much for your help,

Best regards,

Julien
