Bug 313639

Application: k3b (2.0.2)
KDE Platform Version: 4.9.5
Qt Version: 4.8.4
Operating System: Linux 3.7.2-204.fc18.x86_64 x86_64
Distribution: "Fedora release 18 (Spherical Cow)"

-- Information about the crash:
- What I was doing when the application crashed:

I've ripped one dvd (video) and stayed in the window where the chapters are listed, ejected the dvd and inserted a new one. Suddently K3b crashed, apparently when reading the TOC.

-- Backtrace:
Application: K3b (k3b), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
