BGP is not able to use the default route for next-hop recursion, as
you found out yourself. ;) This is as expected.
To fix it, either set the advertising router to set the next-hop to
itself. Or on the receiving router a route-map with set ip next-hop
(which may require recursion ;)). Or advertise the subnet/prefix where
the next-hop is into your igp.

HTH!
