The only way I know is to set font-log to nil before you do this, and
then look at the log.  But I have never learned anything useful from

Look at the DejaVu Sans Mono issues, I think they are the same font,
basically.

Anyway, can you confirm that using other fonts instead of DejaVu Sans
does work?
