VLC v1.0.0 running in WinXP on intel core duo.
when starting [audio]->[visualizations]->[goom]
and [Tools]->[Effects and filters]->[Video Effects Upper tab]->[Image modification lower tab]->[psychedelic check box]
the result is crash: either non responding and audio is looping the last second or so, or XP completely shuts it down.
the order of the two actions above is non-important.
my guess is that it is not XP related and can be reproduced on other platforms.
thanks
