Application: k3b (2.0.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-13-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- Put DVD into DVD-ROm drive and close tray.
- From the drive options menu that pops up, choose "Rip Video DVD Titles with K3b".
- K3B starts and immediately crashes.

Prior to this i had installed libdvdcss2 and transcode. Tried ripping via aforementioned method, but K3b already segfaulted.
I rebooted, but the segfaults kept happening.

The crash can be reproduced every time.

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