WordPress MU

I've just updated from 1.2.4 to 1.2.5a. My Mu site is on a sub-domain, http://uninaplo.unitarius-halo.net , and so uses sub-directories for user blogs, for example, http://uninaplo.unitarius-halo.net/marko-laci . I currently have only three blogs with multi-page archives.

Within Mu links to all blogs are taking the form http://uninaplo.unitarius-halo.net/user . From this address the previous or next page links are directing to http://uninaplo.unitarius-halo.net/user/user/page/2/ (instead of http://uninaplo.unitarius-halo.net/user/page/2/ ) and so leading to a 404 error.

If I browse to http://uninaplo.unitarius-halo.net/user/ the links display and function correctly.

The paths are listed in the site's _blogs database table as /user/ and in the individual blog's _options table as http://uninaplo.unitarius-halo.net/user/ .

This is a new problem. Any help will be appreciated.

Note:

The short urls ( http://uninaplo.unitarius-halo.net/user ) are showing up in the ada updated blog widget when it calls for the URL and in the header of theme packages.

In some blog themes the header link is coded:
href="<?php echo get_settings('home'); ?>/"
this works. In others its coded
href="<?php echo get_settings('home'); ?>"
and this doesn't.

Probably not a Mu problem strictly speaking.

Is there any way to force http://uninaplo.unitarius-halo.net/user to http://uninaplo.unitarius-halo.net/user/ using .htaccess ?
