you can avoid thesae kinds of problems by using RefPtr<>s to store
pointers to FieldContainers in your data structures.
I assume you have a set of MaterialPtr variables in your GUI containe
and you assign these to the objects you want to manipulate. If you use
RefPtr<MaterialPtr> instead it automatically calls addRefCP when you
assign it a new variable, and subRefCP when it's changed to another one
or when it's destroyed (which also takes care of zombies). You need to
#include <RefPtr.h>, but the usage should be the same.

Refcounting is something many people struggle with, no lameness
involved.
Hope it helps
