I think you got it right and this is a known bug
http://bugs.squeak.org/view.php?id=6535
The fix cannot be loaded automatically because the ordre of changes
matters and I did not care enough of it...
But you can load the changes in a ChangeList thru the FIleBrowser and
manually file in change by change in the interim if you are
interested.
