gnome-sushi doesnt work in unity 3d [closed]

Question

I installed gnome-sushi and try to test it, but it doesn't work. I tested it by typing "sushi" into Terminal it doesn't work. I get an error message.

(sushi-start:20986): Gdk-WARNING **: The program 'sushi-start' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadLength (poly request too large or internal Xlib length erro'.
  (Details: serial 221 error_code 16 request_code 155 minor_code 30)
  (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.)

I tried it by logout and login but it doesn't work. I know that it should work with both unity and gnome-shell. I tested it from Terminal with sudo sushi and tried to preview a file in nautilus and get this error this time:

Could not load classifier cascade /usr/share/opencv/haarcascades/haarcascade_frontalface_alt2.xml

I searched a lot but didn't find a solution for my problem on the net and decided to ask you.

Thanks in advance

I don't think that's how you use it. I've installed gnome-sushi on my 11.10 desktop, and now can use it just by selecting a file or folder in Nautilus and pressing Space to open a preview. AFAIK you shouldn't need to run it from a terminal.
