This doesn't solve the case:
- create a page with nav_title
- create a page at same level without nav_title, but with same title as 
nav_title of first page

Same goes for all the other fields in segTitleFieldList.

I think the solution lies inside realurl:
- when installing check relevant fields on all levels in pagetree
- eval functions on fields in page records to check uniqueness, taking 
segTitleFieldList into account
- configuration editor in realurl, checking relevant fields when saving 
the configuration

Not trivial, but then again, realurl isn't trivial either :-)
