Hello,
I am converting a pure latex beamer to a Lyx beamer file. I get a very
strange error that puzzles me. I have searched the net and tried different
things in the exported Latex file, but if I keep the bibliography, the
problem remains. I do not know where to search any more and calling on you,
hoping that you would have an idea about where to look.... I give the
corresponding elements below (follow the *** ).
**** The error I get:

*** I can indeed see such instructions in the bbl file introduced by
Bibtex. I have choosen Natbib (author-year,plainat) in Lyx as the
bibliography style.

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.
