I've been working (off & on) at something of a "howto" on OOo
Writer's lists. Here's the section that I did for this problem:

Hope it's helpful; if not, let me know how to improve it.
It answer the question perfectly: OpenSymbol (OO's default font for
Insert|Symbol) has a taller linespace (for a given point size) than
whatever text font the author happens to be using, so Writer adapts to
the taller font. That's the right and simple answer, but it leaves a
couple of wrinkles, which go beyond the immediate problem but are
germane and would enhance the value of your already valuable explanation:
- Is there normative relationship between point size and line height? If
not, what does point size mean?
- Cor found that he had to go to /half/ the nominal point size (in
OpenSymbol) to match the line height of his text font (I forget what
that was) - for example, 10pt OpenSymbol to a 20pt text size. This seems
like quite a jump. Is there anything in the font specs that can guide a
user to matching an OpenSymbol character to the characters in the text
font (or more generally, any character in one font to the size of
another font)?
Sorry, I realize these questions are easier to ask than to answer, ...
Not in this case because the answer is: I don't know. ;-)
I /assume/ there is some "design line height" parameter stored in the
font--probably based on the maximum character height, from lowest
descender to highest ascender--and that's what Writer bases the line
spacing on. Different fonts have different heights, and even one
character in a different font can bump up the line height.
Just take a normal paragraph and change the font of one word (or one
character--a space or a period, even) to OpenSymbol: you will probably
see the line spacing increase for that line of text.
I doubt this is a bug in the font. My guess is that OpenSymbol simply
has a taller design height than most fonts because some symbols in the
font extend particularly far above or below the baseline.
I don't know of any way to tell for sure exactly what characters, in
what font, face, size, etc., Writer is emitting. Well, ok, I expect it's
there in the PostScript data sent to the printer--I'll be happy to let
someone else track that down. ;-)
