This is the culprit. Loading into 30807 gives the broken behavior.
Here's a snippet of the call chain:
MultiByteFileStream(WriteStream)>>space
EyeInspector(Object)>>longPrintOn:limitedTo:indent: in Block: [ :title :index | ...
Array(SequenceableCollection)>>withIndexDo:
Array(SequenceableCollection)>>doWithIndex:
EyeInspector(Object)>>longPrintOn:limitedTo:indent:
