I'm trying to load a Metacello Configuration I use in Pharo 2 into a brand new Pharo 3 image. However I'm getting an error when attempting to load it, and it opens the emergency evaluator. In the console I see following stack, which repeats over and over: LRUCache(Object)>>error: LRUCache(Cache)>>at: ScrollBar class>>arrowOfDirection:size:color: ScrollBar>>upImage ScrollBar>>updateUpButtonImage ScrollBar>>initializeUpButton ScrollBar>>initializeSlider ScrollBar(Slider)>>extent: ScrollBar>>extent: ScrollBar(Morph)>>bounds: MorphTreeMorph(ScrollPane)>>hResizeScrollBar MorphTreeMorph(ScrollPane)>>resizeScrollBars MorphTreeMorph(ScrollPane)>>hideOrShowScrollBars MorphTreeMorph(ScrollPane)>>setScrollDeltas MorphTreeMorph>>adjustSubmorphPositionsOf:startIdx:startPos: MorphTreeMorph>>adjustSubmorphPositions MorphTreeMorph>>innerWidgetChanged MorphTreeMorph>>privateUpdateColumnMorphs MorphTreeMorph>>updateColumnMorphs MorphTreeMorph>>addSubmorphsFromNodeList:previouslyExpanded: MorphTreeMorph>>updateContentsWithPreviouslyExpanded: MorphTreeMorph>>updateList MorphTreeMorph>>update: PackageTreeModel(Object)>>changed: in Block: [ :aDependent | aDependent update: aParameter ] DependentsArray>>do: PackageTreeModel(Object)>>changed: PackageTreeNautilusUI>>updatePackageView PackageTreeNautilusUI(AbstractNautilusUI)>>mcWorkingCopyCreated: WeakMessageSend>>value: WeakMessageSend>>cull: Error: No factory specified Any clues?
