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
