lilypond-2.1.0-2 - many notes an octave too low

[lilypond]

From the tutorial example showing "the key signature, accidentals and 
ties in action":
\score {
    \notes {
        \time 4/4
        \key g \minor
        \clef violin
        r4 r8 a8 gis4 b
        g8 d4.~ d e'8
        fis4 fis8 fis8 eis4  a8 gis~
        gis2 r2
    }
    \paper { }
}

The result from debian package lilypond-2.1.0-2 is:
address@hidden:~$ lilypond try.ly
lilypond (GNU LilyPond) 2.1.0
Running usr...
Now processing: `try.ly'
Parsing...

DVI output to `try.dvi'...
PDF output to `try.pdf'...
PS output to `try.ps'...
address@hidden:~$

The viewed output (in acroread) shows *all* notes *except* the E natural 
at the end of bar 2 to be *one octave* too low.

This seems like a bug... Is there a detour?

Thanks for all your work on lilypond.

PS: The reason I am using 2.1.0 is beause no Debian package of any 
stable version since 1.4 is available on the Debian mirrors.
