...and the stacktrace from where the error occurs looks like it is related to dri2.

Gdk-ERROR **: The program 'gnome-falling-blocks' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAccess (attempt to access private resource denied)'.
  (Details: serial 47 error_code 10 request_code 2 minor_code 0)
  (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.)


Program received signal SIGTRAP, Trace/breakpoint trap.
