#501 Crash when creating ISO

[Ari Simonen]

I'm trying to create a simple test ISO with one menu for a VOB video file (created using Kdenlive). The menu contains two buttons with "video look".
Every time I try to create the ISO file, DVDStyler crashes.

Here are the details from DVD generation process:
DVDStyler v2.3.4
Linux 3.6.8-1-ARCH i686
FFmpeg: libavformat 54.29.104, libavcodec 54.59.100, livavutil 51.73.101
Prepare
Cleaning temporary directory
Search for transcoded files in cache
Generating menus
Generating menus 1 of 1
Create menu MPEG
Multiplexing subpictures into mpeg
Menu has 1 group(s) of changeable colours.
