I have a hard time explaining this bug unless it is related to the other lazy sequencing scenario being investigated in #28 already. I'm only adding another assert statement to check an internal invariant prior to the code that threw the exception in your stack trace. We'll need to investigate those revised stack traces if you encounter any more errors...

This cannot seem to be reproduced and there are doubts about the server state at time of error...
