This is a configuration issue. The scenario you descibe
indicates Area 0 has partitioned with R4 all by itself.
When area 0 partitions routes break regardless how
small. For standard topologies, virtual links may be
used to repair the break. NSSAs and Stub areas do not
have that luxury/cluge.  An area 0 secondary link across
Area 2 would also work provided you have an
implementation of draft-ietf-ospf-mlinks-03.txt, which I
hope to repost one of these days with some corrections
that others have noted.
