 Yes, it crashed. However I noticed vlc is complaining about the --ffmpeg-
 threads parameter: "Warning: option --ffmpeg-threads no longer exists.".

 And I realized that the vlc and ffmpeg are not from opensuse 12.3
 repositories, but from Packman.
 (http://packman.inode.at/suse/openSUSE_12.3/Essentials):
 vlc-2.1.2-186.2
 ffmpeg-2.1.2-2.1
 libacodec55-2.1.2-2.1

 Sorry for not mentioning it earlier.

 > Which video output module are you using? Does it also crash with {{{-V
 dummy}}}?

 If I am not mistaken, XVideo:
 {{{

 I couldn't reproduce it with {{{-V dummy}}}. I have let it run many times,
 hopefully I wasn't just (un)lucky.
