Look at SmalltalkImage >> changeImageNameTo:

changeImageNameTo: t1
�� self imageName: t1 asSqueakPathName.
�� LastImageName := self imageName

Here, it is putting to LastImageName the new one. Shouldn't be in the other order, like this:

changeImageNameTo: t1
�� LastImageName := self imageName
�� self imageName: t1 asSqueakPathName.
��
Maybe I misunderstood what LastImageName is

Thoughts?
