[squeak-dev] Project Loading 3.9, 3.10

I cannot reload a saved project back into the same 3.9 image or into
the latest 3.10 (both "dev" images). It seems
"RenamedClassSourceReader" is not implemented. This is documented as a
'new' and 'major' bug in mantis from 01-11-07
(http://bugs.squeak.org/view.php?id=5720). Any work-around?
