Product: [Applications] k3b Reporter: James Cain <dequire>
Component: generalAssignee: Michał Małek <michalm>
Status: RESOLVED DUPLICATE

Sentry Crash Report:

Description James Cain 2012-12-28 19:14:12 UTC 
Application: k3b (2.0.2)
KDE Platform Version: 4.9.95
Qt Version: 4.8.3
Operating System: Linux 3.7.0-7-generic x86_64
Distribution: Ubuntu Raring Ringtail (development branch)

-- Information about the crash:
- What I was doing when the application crashed: Adding audio files to a CD project. Clicked on a txt file by accident and crashed. Re-tried and this time clicked on a .jpg file and it also crashed. Reproduceable every time. 

Please note that I did not mark this as a duplicate bug, as all of the others I looked at were crashes caused by adding vairious audio files (mp3 and PLAC), whereas on my system, audio files get selected, analyzed, and added to the project just fine.

The crash can be reproduced every time.

-- Backtrace:
Application: K3b (k3b), signal: Segmentation fault

Comment 2 Christoph Feck 2013-01-10 14:29:52 UTC 
Which version of the FFMPEG libraries do you have installed?
Comment 3 Christoph Feck 2013-01-19 19:15:29 UTC 
If you can provide the information requested in comment #2, please add it.
Comment 4 James Cain 2013-01-20 01:13:52 UTC 
Hello. Muon package manager shows FFMpeg as 6:0.0.4-0Ubuntu2.
Comment 5 James Cain 2013-01-20 01:14:37 UTC 
Sorry - make that 6:0.8.4-0Ubuntu2
Comment 6 Christoph Feck 2013-01-20 01:44:18 UTC 
Woah, that is quite old, considering that you are using a development snapshot of Ubuntu. Please ask in an Ubuntu forum, how to update FFMPEG to 0.11 or newer, and report back, if this fixes the crash.

Well,  I think the poor debian/ubuntu ship (stupid) libav instead of the real ffmpeg.
