As far as I can tell, the destructor of CacheItem is *not* called when cache_item_.reset() is called. When I save sc_ and disconnect sc_ in CacheItem::Impl, the crash persists. This may be because this cached_item_ is referred by both original and copied GraphicInset. Therefore, the disconnection should be done in GraphicLoader, NOT CachedItem, and no destructor is involved. Cheers, Bo
