I _think_ it's unlikely. It's a fairly common pattern to use default images in a table then lazily loading "better" images. In such cases dismissing the view controller (showing the table) while some images are still loading happens often… > Why am I asking?

Rolf added more details (e.g. the selector name) when this exception occurs. This will be available in our next release (5.3.6, already in progress) and should help you (and us) better identify why those cases occurs (leading the way to better fixes).
