Probably because you are using old sources. This issue should be gone by:

  * lib/diarenderer.[ch] lib/textline.[ch] lib/libdia.def : instead
  of throwing away the alignment information in DiaRenderer::draw_text
  pass it through DiaRenderer::draw_text_line so it is still available
  for renderers just implementing DiaRenderer::draw_string

I'd prefer a different way to scale than another export dialog. IMO no 
export filter shoud create it's own GUI, e.g. they are supposed to work in 
batch mode, too.

Please look at plug-ins/libart/export_png.c for the only example for an 
extra dialog during export.
