Bug 302322

Application: k3b (2.0.2)
KDE Platform Version: 4.7.2 (4.7.2) "release 5"
Qt Version: 4.7.4
Operating System: Linux 3.1.10-1.9-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

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

- Unusual behavior I noticed:

K3B crashes when copying a DVD.  I also noticed that dvdrip has some related behavior - when it tries to read the table of contents, memory fills up!  I can watch it climb up to 16GB (the size of my system) and then everything freezes.  I assume this happens in K3B also, but it crashes before the memory fills up.  So the DVD encryption is hostile to the OS.

OpenSuSE 12.1  x64 
Phenom II x6 black
16GB memory

The crash can be reproduced every time.

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