Thanks for these suggestions. First, I had tried "fixed". This
worked as expeted. But then I removed the line from the
shape file so that it was as it was before and restarted dia again.
I was quite surprised when I realized that things now worked
as I would like them to: the aspect ratio was correct,
as defined in the shape file, and the shape was freely scalable.
I found out that the reason was that when I ran Dia with the
shape changed to fixed aspect ratio, Dia altered the default
settings for this shape, so that following appeared in the
defaults.dia file:
      <dia:attribute name="elem_width">
        <dia:real val="7"/>
      </dia:attribute>
      <dia:attribute name="elem_height">
        <dia:real val="1.16667"/>
      </dia:attribute>
instead of
      <dia:attribute name="elem_width">
        <dia:real val="2"/>
      </dia:attribute>
      <dia:attribute name="elem_height">
        <dia:real val="2"/>
      </dia:attribute>
for all other non-fixed asp. rat. shapes in this sheet.
After removing the aspect ratio line from the shape file,
Dia just kept applying these new default settings.
