I was going to suggest putting (setq font-lock-verbose nil) in your .emacs (which has helped symptoms like this in the past), but I think the issue is something else. See below.

My guess is that you may be running into the 10.8 mach_port_allocate_name() lossage. (It's a long, horrible story.) See http://trac.clozure.com/ccl/ticket/1005.
Please upgrade to the CCL 1.9 release, where we avoid direct use of the Mach exception handling interface.
