It would be nice if GeoServer could help more in identifying this sort of
problem (I've committed a patch to make the REST API less forgiving of
broken configuration, but it won't be in a release until the 2.2 series.)
However, usually the problem can be identified (and often corrected too)
through the REST API as well.  My first pass is to use a small script with
gsconfig to enumerate through all fields, then search through that for
fields set to None to identify problems.  Here's an example (it should work
fine with the gsconfig in the GeoNode installation.):

A common problem is to have the latlon_bbox field set to None (and often
that is paired with the native projection not being detected.)
