 Thanks for the report.  This is definitely a bug; the register check
 shouldn't be done when no process is running.  Unfortunately it is a
 little tricky to fix... until the ? packet is sent, we do not know if
 the process is running yet.  But until we have a description, we can
 not fully parse the reply to ?.
