K3B does NOT deal with Blu-Ray blank disks properly

[alizard]

Binary package hint: k3b

he problem is with K3B, not my system configuration. Nero Linux 4 is burning a Blu-Ray disk as I write this and has already burned two others without error using read-after-write verification.

Found medium: Empty BD-R medium

Plese insert a suitabl medium into drive

HL-ST-ST BD-RE WH08LS20 (/dev/sr0)

Appears not to be a permissions problem, while Nero Linux said there was a problem, I solved it and it burned.

The permissions that worked for Nero Linux did NOT work with K3B, I got the same message after changing permissions
and for that matter, even when running K3B as root.

dmesg output:
