[squeak-dev] MNU UndefinedObject>>do: inside ImageSegment>>comeFullyUpOnReload:

Casey Ransberger
When I was messing around with the object palette I noticed, after clicking on the tools tab, that a dialog appeared which said "Reading a stream," a few seconds after which I see this stack (looks like arrayOfRoots is nil, maybe because it couldn't find the stream it was looking for:)
