Comment 1 Thiago Jung Bauermann 2011-04-18 00:00:06 UTC

This bug also happens to me. I was trying to rip my "Concert for George" DVD and k3b crashed with the same backtrace.

Before I installed transcode k3b didn't crash. It just complained that it needed transcode. After I installed it, I hit this bug.

I'm using Debian unstable, with k3b package version 2.0.2-1+b1 and KDE 4.6.1 from the semi-official KDE repository (http://qt-kde.debian.net/).

My transcode package version is 3:1.1.5-0.8.

[Comment from a bug triager]
Bug 267684 has a similar backtrace.

From bug 277153:
-- Information about the crash:
I was having problems ripping a DVD so I closed out of the program.  Once
closed it the program generated a crash report.  This happened three times in a
row.

k3b (2.0.2) on KDE Platform 4.9.2 using Qt 4.8.3

- What I was doing when the application crashed:

When launching K3B via the Device Notifier widget (ie when you stick a DVD in and you get asked what you want to do with it).  I click on 'Rip DVD', K3B opens, and segfaults immediately.  

Works fine if I open the program first then click on 'Rip DVD'.

k3b (2.0.2) on KDE Platform 4.9.4 using Qt 4.8.3

- What I was doing when the application crashed:

clicking on "Rip Dvd with k3b" from KDeviceNotifier, k3b starts and crashes.

k3b (2.0.2) on KDE Platform 4.10.5 using Qt 4.8.4

I can rip a DVD successfully all the time, when it's the first DVD of the k3b session.  If I insert the next DVD, then it almost always crashes (once it did not).  If I quit k3b and start it again, it works fine on the same DVD.

- What I was doing when the application crashed:

After initial startup of K3B, I selected DVD-rip from the menu and it crashed.  Also crashed after first inserting a video DVD and KDE pop-up asked what to do (I selected rip video with K3B), upon which KDE started up K3b and K3B proceeded to crash.  I cannot rip DVD video via K3B.

Comment 37 Martin 2015-04-02 09:04:58 UTC

This issue has already been marked as resolved in version 2.0.3. Since you are using 2.0.2 I would advice you to update your version of k3b.
