I can't reproduce this. For me, it works fine:

$ dia --export-to-format=png --export=Diagram1.dia.png.tmp Diagram1.dia
Diagram1.dia --> Diagram1.dia.png.tmp
$  file Diagram1.dia.png.tmp
Diagram1.dia.png.tmp: PNG image data, 56 x 45, 8-bit/color RGB, non-interlaced
$

This certainly doesn't conform to Unix conventions but is not
necessarily a bug. Feel free to discuss this with upstream at
dia-list@gnome.org or send in patches for improvement.

Thanks.
