Version: 0.12.8 (using KDE KDE 3.4.2) Installed from: Slackware Packages Compiler: gcc (GCC) 3.3.6 OS: Linux k3b will crash on some (not all) encrypted DVDs when trying to copy DVD or copy DVD only to *.iso image. The problem is repeatable. Details: system: GNU/Linux Slackware 10.2 kernel: 2.4.32-rc1 cdrtools: cdrtools-2.01-i486-1 cdrdao: cdrdao-1.1.9-i486-1 dvd+rw-tools: 5.21.4.10.8-i486-1 libdvdread: 0.9.4 libdvdcss: 1.2.9 DVD drive: NEC Model: DVD_RW ND-3540A Rev: 1.01 k3b will crash almost immediately after clicking "start" in dialog windows of DVD copying, after displaying a few lines about reading encrypted DVD and something about keys - it is displayed for too short a period to take note of it. The debug information is: Using host libthread_db library "/lib/libthread_db.so.1".

actually, KDE was installed from packages and k3b 0.12.8 was compiled from sources. Previous version of k3b (installed from the package), the one included in Slackware 10.2, would crash on ANY encrypted DVD
you may run k3b through gdb with --nofork
First, I changed the kernel to 2.4.32. The problem persisted. The gdb follows: Here we start...

But why doesn't the kernel panic? Or is it a problem with libdvdcss, anyway? What is the exact command k3b uses to generate the iso? I might run it manually from the console and check.
there is no command. It crashes inside libdvdcss which does not nessessarily mean that there is no bug in K3b.... but I don't know where... I will have to look into that.
I found the cause - it was neither a bug in k3b nor in libdvdcss. The problem was that the dvd region of the drive had not been set. I found the solution at http://forum.videolan.org/viewtopic.php?t=9386. The regionset program from http://linvdr.org/projects/regionset/ fixed it. There is still, however, the bug (feature?) which causes k3b to block the drive when copying dvd to dvd. When after creating iso there is the dialogue to eject/force/cancel the tray, only "cancel" is active. I can of course first "only create iso", then manually unblock the drive from the menu and then press "burn dvd from iso", but isn't it too much work? ;-) I found the description of this bug here, but the suggested solutions (turning off/removing all the automouts/autostarts) would not work - I do not use any of them, anyway. It is not a major problem, though.
the blocking issue is fixed in 0.12.12.
