I see. Well, pdflatex seems to understand the quotation marks as well 
plus it solves the problem with the PDF bookmarks. And I guess there are 
certain problems I might run into when switching from pdflatex to xetex. 
So the switch isn't costless.

I see. Couldn't LyX remember whether the switch has been made and delete 
those aux files. I guess the error is not a big problem but I was 
already thinking that it did not work correctly.
