That's one thing that I had a lot of problems with, it's a real pain
finding "unused" fonts in a Scribus document to prevent them from
being embedded.

One would think that only fonts that at really used would be embedded,
but as far as I understand Scribus will even embed all fonts that are
used in styles, even if some of those styles are never used in the
document.
