In this case there was a const barrier which needed to be penetrated,
triggering all of this.. Probably a design error somewhere (missing
write access method, or the code in question executing in the wrong
context).

The latter I think here.. this kind of objects is best copied
explicitly, and C++ is a bit too keen on making copy easy via the normal
methods..
