stem direction programming error |

Hello all,
I've got the following code in a solo violin score:
r4 << { \voiceOne b'( c) } \new Voice { \voiceTwo <d,! \tweak
#'duration-log #4 g,>2 } >> \oneVoice <ef \tweak #'duration-log #4 g,
d''>2\downbow \typesetOff <a ef f'>2 ~ | % 3
<a f'>4\mf ef' \times 2/3 { d4\tenuto af bf } \typesetOn b8 e,!
\> b! bf | % 4
where \typesetOff and \typesetOn are shorthand for \set-ting the
Score.skipTypesetting property.
When I allow the non-typeset blob
<a ef f'>2 ~ <a f'>4\mf ef' \times 2/3 { d4\tenuto af bf }
to be typeset [i.e., remove the \typeset commands], I get
Preprocessing graphical objects...
programming error: Stem dir must be up or down.
continuing, cross fingers
and then Lilypond fails (i.e., Lilypad simply brings up the
previously-typeset version of the PDF file).
Unfortunately, I can't seem to duplicate the behaviour in a minimal
file, but I was hoping someone could look at this code and tell me
what could possibly be wrong with the little excerpt that's causing
the problem. [I'm using 2.12.2 and 2.13.3 on Mac OS X 10.4 — both
versions fail while trying to typeset the chunk.]
Thanks!
Kieren.
