  I noticed there were an obsolete class in 3.0 image, too.
Anyway, I figured out the problem with the Tracer was that
the #allBehaviorsDo: method doesn't traverse the obsoleted
classes.

  I posted a fix for this on June 29th.  See
http://groups.yahoo.com/group/squeak/message/30627
(The fix looks a little rough and doing unnecessary things,
but should work at least.)

  Hope this helps,
