Wow. I bow to the depths of the Squeak neural connections that must be going
on in your brain...
I can only seem to find stuff like that in procedural languages when I don't
know the system at all.
Anyway, you are right! All I did was recompile PluggableTextMorph>>drawOn:
and Smallalk condenseChanges ran to completion.
I'm not quite sure how to test the Trait problems mentioned at the beginning
of the thread to see if they are fixed by this, though...

----------
When parsing #asCharacter, the UTF8 encoder fails with an
errorMalformedInput because it seems to read back to the strange dot
character.
The question is whether this character should not be used, or whether
parsing is bogus. Looking at #backChunk and related methods, latter
seems possible. Looks a bit fishy with sends to #oldBack,
#oldPeekBack, but also to #back. Damien, can you verify your changes
in these methods?
As a workaround recompiling PluggableTextMorph>>#drawOn: solves the
problem (because then the source position of this method is moved away
from the asCharacter method).
