Bug 215817

Application that crashed: k3b
Version of the application: 1.68.0
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.3
Operating System: Linux 2.6.30-gentoo-r6 i686

What I was doing when the application crashed:
K3b crashes at some random point when copying a dvd using the "copy medium" function. I've tried a handful of times, but it crashes everytime after some random time.
