Xine based players are not working anymore (X config/driver issue affecting Xv)

[Ryiden]

All xine based players are not working anymore in gutsy.
gxine exits with the following error message:
Code:
The program 'gxine' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 326 error_code 8 request_code 140 minor_code 14)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

xine exits with this error message:
Code:
Dies ist xine (X11 gui) - Ein freier Video-Player v0.99.5.

Bug 126207 (xine-lib) may be relevant.
