Found the use case.
Steps to reproduce it in your Squeak 6.0a trunk image:
a) In a regular MorphicProject choose 'show shared flaps' (right-click
world menu in my setup)
b) from the 'widgets' flap bring out a paint tool
c) draw a sketch / select 'keep'
d) bring up the halos of the sketch
e) choose the blue 'viewer' icon
f) drag out the 'sketch turn by 5' tile from the tiles of the sketch
you get the error message
SmalltalkImage>>#associationAt:ifAbsent: has been deprecated. Use
