mplayer dont working with xfce

[Guilherme Albuquerque Zalochi]

 Hi all
 
 
 Why my mplayer dont working in xfce?
 
 i recive this error 
 X11 error: BadAccess (attempt to access private resource denied)
 
 
 MPlayer interrupted by signal 6 in module: decode_video
 - MPlayer crashed. This shouldn't happen.
   It can be a bug in the MPlayer code _or_ in your drivers _or_ in your gcc
   version. If you think it's MPlayer's fault, please read DOCS/bugreports.html
   and follow the instructions there. We can't and won't help unless you provide
   this information when reporting a possible bug.
 
 
 in another windowmanager mplayer works is fine
 
 
 
 
 tks
