While iterating over all the keys stored in the source Dictionary
to copy them to create the copied Dictonary, the name of the key
being copied was only set to a non-NULL value for the first key
we copy. This was then leading to an assertion when trying to
create a std::string from a NULL pointer. Simple test-case:
int main()
{
PList::Dictionary a;
PList::String b("Hello");
PList::String c("Hi!");
PList::Dictionary d;
a.Insert("Key", &b);
a.Insert("Another Key", &c);
std::cout << a.ToXml() << std::endl;
d.Insert("dictionary", &a); //CRAAAAAAAAASH!
std::cout << d.ToXml() << std::endl;
return 0;
}
