STDERR: 
STDERR: warning: core file may not match specified executable file.
STDERR: 
STDERR: (WebKitWebProcess:126601): Gdk-ERROR **: 12:27:50.579: The program 'WebKitWebProcess' received an X Window System error.
STDERR: This probably reflects a bug in the program.
STDERR: The error was 'BadAccess (attempt to access private resource denied)'.
STDERR:   (Details: serial 855 error_code 10 request_code 130 (MIT-SHM) minor_code 1)
STDERR:   (Note to programmers: normally, X errors are reported asynchronously;
STDERR:    that is, you will receive the error a while after causing it.
STDERR:    To debug your program, run it with the GDK_SYNCHRONIZE environment
STDERR:    variable to change this behavior. You can then get a meaningful
STDERR:    backtrace from your debugger if you break on the gdk_x_error() function.)
