Observe that (.*) will happily match a - within an URL, making a number of these matches ambiguous, and possibly very slow. Your \w matches most likely be preferable.

Are you able to paste the diff(1) involving the last known good working .htaccess and that one? That will assist you in finding the fault rapidly.
