The problem seems to be with natbib in my case. If I choose implicit in the
document bibtex properties and use harvard.sty with the agsm style for my
bibliography, it works.
I like the flexibility of Natbib for citing references.
While using natbib, I have tried plainnat and several authord-date bibtex
styles. Am I doing something stupid? Are these styles compatible with
Natbib (plainnat seems to be, given the information I have read in the
Natbib documentation pdf).
Very strange... Because I have been able to use natbib with LyX before, I
am very surprised by this problem. As you can see in the extracts of the
..bbl file I have attached, all main fields of the references (like title)
are transformed to "newblock" when I use Natbib + author-year in document
properties and plainnat in the references style box, at teh end of my
document.

Hello,

Hi,
If I remember correctly I think \newblock is usually defined by the BibTeX
style file (.bst file) just like \url, \doi, etc. If that's right then
you're seeing a bug in that style file.
You can quickly fix it by defining this command yourself in the preamble
of your document.

Hi Murat,
What I wrote earlier about \newblock being defined by the style file was
wrong. It is defined by natbib.sty but somehow undefined when used
together with beamer.cls; some googling revealed that this is a known
incompatibility problem between natbib and beamer, and the solution is
\def\newblock{}
in the preamble.
Cheers,
Julien
