Application that crashed: k3b
Version of the application: 1.69.0
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32-3.slh.3-sidux-686 i686
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
This time, my home directory has plenty of space, and also the system was rebootet quite shortly before, so I wonder what reason there could be?

Maybe a bad Platinum DVD-RW? Out of a box of 5, only one would be readable after burning, all the others cannot be read or anything. There ID is not recognised either (as opposed to the single good one).
