This error appears *only* in simulated mode and it does not mean that
real recording will fail with same error. In other words failure to
close the session is *limitation of simulated mode* and should be
disregarded. Purpose of simulated test is rather to see if your system
sustains the load.

I don't know exact details about K3b verification procedure, but I know
that verification becomes tricky if you try to rely on table of content
to determine how much of burned data to verify. Turn to K3b people (the
matter was discussed with them) or mount burned media and originating
image and verify file by file, e.g. 'find . -type f -exec md5sum {} \;'.
