MessageNotUnderstood: MaMalformedRequestError>>repositoryController:

[Chris Muller]

Hi Hilaire, a the MalformedRequest error is telling you the server
received a request from your client that it could not properly
materialize.  Specifically, it looks like your Magma client has
attempted to extend the Magma #protocol ("class id not found").  Are
you running a modified Magma client?

It does look like the error-handling code incorrectly passes the
MalformedRequestError Exception AS the request which is, of course, a
bug.  I will fix that, so that it kick the error back to your client
as it should.

But I know you are interested in the cause of the error itself.  When
you get this error, you should break into your client and look in teh
debugger at the request it passed to the server.  Look at ALL the
arguments and find which object whose class is not included in this
Array:

  MagmaRepositoryController basicNew protocol

THAT is the one that is causing the problem.
