And than you got upset that it didn't work, at least that's how I 
understood you complaints ;)

Huh? Where did you get that information from? If Dia would work natively 
with SVG why would there be three SVG exporters and two SVG importers?
(Maybe you are confusing Dia with Inkscape/Sodipodi, which indeed have 
native SVG support.)

Dia's icons are loaded via gdk-pixbuf and even though the dia-installer 
version seems to have pixbuf/svg support it does not seem to work very well.
But even if that would work, I fail to see the benefit of rendering icons 
via SVG; by using the shape exporter there is one created for you with Dia.
It even was included in your shape set.

Maybe the same issue you have with Dia/gdk-bixbuf using your SVG.

Technically speeaking, I don't think it is a crash at all. Running 
Steffen's build from console gives:

[...]\Dia-0.97.1-0\bin>dia

(dia.exe:1200): Pango-CRITICAL **: pango_win32_font_map_get_font_cache: 
assertion `font_map != NULL' failed**
Pango:ERROR:pangowin32.c:838:pango_win32_font_finalize: assertion failed: 
(win32font->fontmap != NULL)

This application has requested the Runtime to terminate it in an unusual 
way. Please contact the application's support team for more information.

But if you dont think it's useful, why do you do?

There are certainly more things where you can break Dia by doing something 
it is not made for. Complaining about them on the mailing list is not an 
effective way to get them resolved.

Creating a bug report at
        https://bugzilla.gnome.org/enter_bug.cgi?product=dia
has a higher probability to be resolved (one way or the other).
