By setting the VLC audio output to Alsa the faultmessage was reduced to:
(.:11652): Gtk-WARNING **: Kan themamodule in modulepad: ‘clearlooks’ niet vinden,
[00000343] main private error: option glx-shm does not exist
libGL error: drmGetMagic failed

In this bug report
https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/251735
a similar fault is reported
having an Ati radeon 9800 I also use fglrx
Installed the Ati driver with EnvyNG.
When I use mplayer for wmv streams I have very bad quality and 3 or 4 instances of mplayer are opened.

I found the solution for this last set of errors here:
http://ubuntuforums.org/showthread.php?t=419018

open vlc (no video, just open it as a program), and do the following:
click - settings > preferences > video
in the bottom right, put a checkmark in "advanced options"
then click - output modules
and change "video output module" from "opengl video output" to "x11 video output".
