I see. So the comment/experiment was in the lyx file, not in unicodesymbols.

That solved the failure.
It should work now. Unfortunately, I had to invert all Unicode_character
tests, because "export failed while converting"
(see the comment in suspiciousTests).

Not easily (of course, you can `grep` in the sources, try googling for
documentation or tips and tricks, or ask at comp.text.tex).
In case of an error, the log gives some hints: whenever a new file is
loaded, you see a "(" followed by the path. After processing the file,
closing is indicated by ")". If a file loads another one, the () are nested.
This way you can find out which file the code triggering the error is from.
For location of the problem in a LyX file, line-numbers or a search
feature in the source pane would be nice. Until we have such a thing, you
can open the tmp-dir and then open the log with a decent text editor...
