missing noteheads in pdf

I've experienced some very occational strangeness; sometimes (like once
every 10 pages) a few noteheads are missing in the pdf-files. It's the
same place everytime, and it's always missing. The problem has been
there at least since 1.5.7x... Here's how I normally convert to pdf
(which misses noteheads sometimes):

ly2dvi $1
dvi2pdf `basename $1 .ly`.dvi

and I found that first converting to ps and running ps2ps before going
to pdf resolves the problem:

ly2dvi $1
dvips -f `basename $1 .ly`.dvi > `basename $1 .ly`
ps2ps `basename $1 .ly` `basename $1 .ly`
gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sPAPERSIZE=a4
-sOUTPUTFILE=`basename $1 .ly`.pdf `basenam
e $1 .ly`

Now for the questions:

1) Is this a known issue, and if so where is the problem - gs or lily,
and what's the best workaround. If this is not a known issue, I'd be
happy to supply the coders with problematic files in any step along the
two lines.

2) It seems that ps2ps screws up the fonts, at least it looks really
ugly on screen. Since I don't have a printer at home I'm wondering if
the printing still would look good. Seem to remember having heard about
something similar; pdf's that look like crap on screen and prints just
fine, something with fonts for printing and fonts for onscreen

I'm (still...) in lily 1.6.9 on a debian-box. My gs is 6.53.

peace, love & harmony
