Do you use a d-pointer for your classes and if so are these classes copied 
around by the assignment operator? The implicit assignment copies just the 
d-pointer itself AFAICS. This overwrites the original d-pointer and the 
original private object stays without any pointer to it: mem leakage :(.

I've just encountered this problem. Don't know wether my interpretation is 
right though.
