        <pre>(bin/TestWebKitAPI/WebKit2Gtk/TestWebKitWebView:8449): Gdk-ERROR **: The program 'bin/TestWebKitAPI/WebKit2Gtk/TestWebKitWebView' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDamage (invalid Damage parameter)'.
  (Details: serial 514 error_code 151 request_code 143 (DAMAGE) minor_code 2)
  (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 GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
