\incipit sometimes returns programming error

[Thomas Morley]

Hi,

consider:

\score {
  \new Staff \with { instrumentName = "" }  { \incipit { c'1. } R1 }
  \layout {
    indent = 5\cm
    incipit-width = 3\cm
  }
}

with recent versions it returns:
programming error: Loose column does not have right side to attach to.

First bad comit is:

The example above can be fixed by inserting an explicit \bar "" at end
of incipit-music.
