Thanks!

In following scenario, a QofInstance cannot be added into a QofCollection

QofIdType type = "some type";
QofInstance inst = g_object_new (QOF_TYPE_INSTANCE, NULL);
inst->e_type = type;
QofCollection coll = qof_collection_new (type);
qof_collection_add_entity (coll, inst);

The last call will always fail, because coll's e_type has different
address with the original variable type due to invocation of
static_cast<QofIdType>
