Problem using K3B

Debian Sarge running KDE.
I have used K3B in the past without any problems, but after a period of a
month (during which many packages might have been upgraded), I tried to
burn a data CD today.
When I fired up K3B, I found a warning message indicating that cdrecord
permissions were set to root.root and it might lead to performance
problems. I looked into K3Bsetup but it did not give me any relevant
options. So I started anyways.
The buffer fills up to 98 %, 5 % written, and then the CD burner goes wild
- lots of noise but top indicates no relevant process running or even
taking up CPU time.
I cancelled and retried with cdrecord permission change check unchecked in
K3Bsetup, found the following debugging o/p :
K3b Version: 0.11.9
KDE Version: 3.2.2
QT Version: 3.2.3
scsibus: -2 target: -2 lun: -2
Warning: Using ATA Packet interface.
Warning: The related libscg interface code is in pre alpha.
Warning: There may be fatal problems.

Before I had unchecked the permissions change on cdrecord (in K3Bsetup) and
unchecked burn on the fly, I had this additional error message :

The drive is now locked and only a reboot will let me remove the (wasted)
