Preview log contains just the log of the latex run on the preview tex file,
it won't give any hints of what LyX does to the compiled dvi.
I would advise to run reconfigure LyX from the Tools menu, but if that
won't help, I have to pass it to other developers. For me it doesn't create
the pdf file, so I can't say anything, because I can't reproduce. It seems
though, that the lyxpreview2bitmap.py python script is responsible here, so
I ask someone with competence in that.
