Unnecessary page break, leaving lines empty

Unnecessary page break, leaving lines empty

[Huseyin Özoguz]

Hello,

I have an unnecessary pagebreak in the following min-example: the last 
four lines of the first page are left empty, without obvious reason:

\setupinterlinespace[line=3.0ex]
\setupbodyfont[10pt]
\showgrid
\setuplayout
  [location=middle,
   topspace=17mm,
   header=0mm,
   footer=12mm,
   bottomspace=15mm,
   width=middle,
   cutspace=20mm,
   backspace=19mm,
   grid=yes
  ]

\showgrid

\starttext

\chapter{Überschrift}
\dorecurse{260}{hallo wie geht es? }
\section{Überschrift}Text.

\stoptext

The problem seems to be the combination of the layout, bodyfontsize and 
interlinespace. If I change any of them, even by a small number, the 
problem vanishes. Whats the underlying problem and how to solve it 
without changing layout, fontsize or interlinespace?

Thanks.
Huseyin

grid=yes, (missing comma after the setting)

The section pulls the previous line of text to the next page, you can 
avoid this when you allow the section to force a page break.

\setuphead
   [section]
   [before={\blank[preference,2*big]}]
