I'll say; when you subclass ProtoObject, it's easy to forget about
some vital message that's usually handled in Object.

What's a ByteStream? Do you mean ByteString?

You can debug the debugger to find where it crashes. Inspect the
debugger's model, then debug what happens when you send it #send.
That's how I found that the debugger chokes for the first time when a
MessageCapture is sent #class. If I fix that, it chokes for the second
time when it gets #instVarAt:. I'm sure there are more after that, but
I'll let you find them.
