PDF bug or misunderstanding?

[Doug Asherman]

Hello:

I'm a new user of lilypond, and I've run into an issue. The odd thing 
is, this doesn't happen all the time. Context: I'm using teTeX 1.07 on 
Slackware 8.1 (Linux), lilypond 1.6.6.

I have a very simple input file:

\score {
  \notes \relative c' {
     \key g \major
     \partial 4
     c'8 b \bar "|"
   }
   \paper { }
}

if I take this through the steps to produce a pdf file (lydvi input.ly, 
dvips input.dvi ps2pdf input.ps) or just do the one-step thing, I end up 
with a pdf file that has incomplete note-heads. This is using xpdf to 
view the pdf file -- if I use gv, it views ok. But this isn't really 
good, because I have to send the pdf file off to MSWin users.

Here's the odd thing -- if I take the "\key g \major" line out, I get 
good (well, decent-looking) note heads. They're at least readable, anyway.

So -- anyone seen this before? Any workarounds?

Thanks for any replies,
