Subject: Hard lock with a CD-R and k3b

I have a CD-R that makes linux lock hard when I start k3b. I copied these
messages from the console by hand (I hope there are no errors). NB: these
are not kernel messages (there's nothing in the logs and sysrq doesn't
work). This is what k3b prints and I'm aware it's not very useful:

[...]
Diskinfo:
	mediatype:		CD-R
	current profile:	CD-R
	disk state:		incomplete
	empty:			false
	rewritable:		false
	appendable:		true
	sessions:		4
	tracvks:		4
	layers:			1
	capacity:		... LBA 336601 ...
	remaining size:		... LBA 25803 ...
	used size:		... LBA 310798 ...
====
SCSi command failed:
	command:		READ DVD STRUCT (ad)
	errorcode:		70
	sense key:		illegal request (5)
	asc:			30
	ascq:			2
(k3bdevice::device) /dec/hdf:	READ DVD STRUCTURE length det failed
<BOOM>

I'll try the same CD with other kernel versions/archictures. In the
meantime, have you any hints ?
