Thanks, Erik.  I'm afraid I cannot deduce much about this from the
screen shot.  Could you please run Emacs under GDB and when the 
freeze happens again, switch to the debugger, interrupt it and

  (gdb) bt
  (gdb) xbacktrace

The xbacktrace command is defined in src/.gdbinit and prints a Lisp
backtrace.  When you repeat that procedure a number of times,
after continuing execution again, it might be possible to see
where it loops, if it loops that is and isn't stuck in a system
call, for instance.
