Amazingly, it is quite correct that the command works if you split it.  This 
is the same drive, the same disk, the same image:

I guess that that means that k3b doesn't handle rw disks properly - possibly 
because of the need to split the command.

Thanks for the help.  I understand much more of what is happening now.
