Comment 23 for bug 60138

Lajevardi, Can you please "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.)"
See if that gives a better error that can help us more, Please remove any extenstions that you have installed and see if this issue goes away. What graphics card do you have and what drivers are you using?
