Close. There is a SqueakDebug.log that you can send. But the information 
is clear enough - it looks like it's SqueakMap causing trouble again, 
probably during flaps reinitialization. Try destroying the global flaps 
(World Menu >> Flaps >> Destroy All Shared Flaps) before you update. 
This should fix it.
