Separating_line_group_engraver broken

[Stefan Waler]

Hi,

there seems to be an issue in 2.12 with Separating_line_group_engraver 
in combination with Bar_engraver in the Lyrics context - see attached 
example.

If I comment one of these lines, the score is printed correctly.

The log contains the following lines:

Programmierfehler: vertical alignment called before line-breaking
Programmierfehler: minimise_least_squares ():  Nothing to minimise
This means that vertical spacing is triggered
before line breaking

Fortsetzung, die Daumen drücken
