Bug 20734

Description of problem:

I was writing a 2,39 GB iso on a DVD-R disc.
(iso is MSW7proSP1, SHA1 checked OK before writing)
I have selected default fully automatic, plus verify.

It stopped at 96% writing (according to k3b window) with error message 
"Allvarligt fel under inspelning: Ogiltigt argument"
I translate:
"Serious error during recording: Illegal argument"

But real result is:

1) It did eject the tray

2) k3b log show no error in writing. (no error at all, but also nothing abut attempting to verify)

3)  # sha1sum /dev/sr0  give the correct checksum.

-Which reveal another bug: it assumes the error is write error, but write was OK.

(so here really are two bugs)

Normally it ejects the disc and immediately pulls it in again to continue with the verify pass.  This have worked before on cauldron, exact same machine, some time in august.  I believe the error is that it now fail to give a today correct command for the eject+pull in.

WHAT give that notification, because of WHAT command?
