Having issues with new Blog Templates and other WPMU plugins

When a new site is created with a template, your Google maps plugins is broken, until I go in and use the extra plugin tools to recreate/fix the google maps db.

Also new sites with the template plugin installed don't seem to pick up the selected language.

Have therefore dumped the template plugin for now. I'd rather have working sites, post-sign-up than convenience of templates.

Any ideas whether this is fixable?
