Happy New Year to All.
This has been solved (after some detective work) but am reporting
it, just in case it happens to others.
Had a recent mysterious error when trying an Lyx to pdf conversion.
The program reported a Latex error but gave no error report.
The same Lyx file converted to html immediately, no errors. I had
a coding error, ignored by one converter. A look at the source code
was not a success.
So, used the traditional system of halving the file, testing halving
again,
until there only a single line of code left. There was the problem, a
Hyperlink
with a irreconcilable character, a beginning itemize dot, like this :

Removing the dot fixed the problem, but an hour or two wasted looking
for it.
