And in this specific case it is live proxy objects that causes the
problem. When saved proxy objects are accessed later, memory faults
occur because the foreign objects being referenced does not survive in
the saved image. Because of this clg can not be initialized before an
image is saved. When saving an image one should also check that there
are no live proxies with glib::list-cached-instances and do a full GC if
necessary.
