lots of programming errors in 2.1.34

[Erik Sandberg]

hi,

I just got a whole bunch of new programming errors. This fairly short snippet 
produces:

1. A couple of these:
programming error: minimise_least_squares ():  Nothing to minimise 
(Continuing; crossing fingers)

2. The following warning:
/tmp/bee/progerror/piano.ly:5:10: warning: Programming error: Spanner `Beam' 
is not fully contained in parent spanner `VerticalAxisGroup'.:
  es8 es4
          d16 c |

3. A couple of Infinity or NaN encountered.
4. Weird output (no lines in the staff).

Here's the code:

\version "2.1.34"
\score {
\new Staff \notes \relative c'' {
\time 2/4
  es8 es4 d16 c |
  \change Staff=A
  d,16 b' f b d, b' f b |
  <c es,>4 r8
}
  \paper {}
}


& here's the full output:
