Day/Month/Year Permalink Structure Fails in Archives

[Frenzie]

If you use a permalink structure with %day%/%monthnum%/%year% then the archives automatically become date/%day%/%monthnum%/%year%. Wordpress automatically makes the links to monthly archives date/01/2010 etc (which is good), but if you go to it you get a 404 not found.

Reproduce using for example /%post_id%/%postname%/%day%/%monthnum%/%year%/

I "fixed" it with this plugin I wrote, but it will probably fail when things like /page/2/ come into play (that wasn't really important yet).
