Thanks. The relevant portion is this:

	Receiver: <<error during printing>>
	Arguments and temporary variables: 
		classString: 	#PluggableShoutMorph
		metaBoolean: 	false
		selectorString: 	#correctFrom:to:with:
		catString: 	nil
		timeString: 	'tween 6/28/2004 08:11'
		sourceString: 	'correctFrom: start to: stop with: aString

It seems in your image there is a method PluggableShoutMorph>>correctFrom:to:with: that has a category "nil". Monticello fails trying to snapshot that.

As others have pointed out, in Trunk we have Shout already loaded, so things might break if you loaded a different version.
