Problem with slurs, removing stem engraver

[Don Blaheta]

Ok, I found a bug of some sort, and as instructed on every damn page of
the manual, I sent a report to address@hidden (why not
address@hidden), which just got rejected because I'm not on that
list.  I was told to go to some page at gmane.org that took a minute and
a half to load, requires extra confirmation to be sent back and forth,
and doesn't let me attach files, so I figured, screw this, I'll send it
to the development list.  Sorry if this email isn't relevant to you.



It's a twofer!  Or perhaps two aspects of the same bug.  If I compile
the attached file as-is, it claims
  programming error: slur attachment is inf/nan
  continuing, cross fingers
  programming error: slur attachment is inf/nan
  continuing, cross fingers
while compiling, and has an ugly slur.  If I remove the commented line
(thus removing the stem engraver), compilation simply halts after
breaking lines:
  Calculating line breaks...

This is 2.6.4 on a MacOS box.  Incidentally, I think gregorian-init.ly
is calling \version, because lilypond doesn't warn me about lack of a
\version line when I've included it---that probably shouldn't be the
case.

Don't use a big word where a diminutive one will suffice.
