The test case you sent me offlist is now fixed in svn. That test case
doesn't mention DynamicSubclass but I presume that it's the same
problem. Can you check the latest revision from svn* and confirm if
the original issue is also fixed?

Essentially the reason it worked with ->compose_namespace is that it
properly sets up the result class for the previewed source, which the
::Preview code didn't do on its own.
