Well, it seems we do have a problem here. I've exported the file attached
here, and tried to reload in Sodipodi (0.23). The rectangle was black
(correct border), the blue arc didn't appear, and all line widths were way
too thick (like 10 times too thick, "by nose view").

I don't know which of dia (CVS) or sodipodi is wrong. I'd suspect us, but
would like confirmations. 

This is definitely a Normal bug, to be reported in the bugzilla.

I don't know.

A scaling control may be desirable, indeed.

This has been suggested from time to time. It could also be good for PNG
export (to export an image map together with the object). This should be
reported in the Bugzilla as a wishlist, but hasn't been.

As the SVG spec allows that, you can always write a transformation tool to
re-add the event handlers. But as you'll have to fill them by hand anyway,
is it that big a task to manually add handlers ? (I really don't know).

might be a real "bug" (well, minor I think). If you don't know how to fix
it, please report it to http://bugzilla.gnome.org, module "dia", so
bore^Wpeople in search for tasks can pick it up. Also, there are also two
other bugs above, the first one should definitely be reported. You spotted
it, please take credit for reporting it :-)

http://dia-installer.sourceforge.net should have what you want.

AFAIK, it hasn't been done, at least not on the whole tree. It would be good
actually to be able to compile using mingw32 instead of MSVC (this might
help people debug some Windows issues using WINE... or Wine issues more
certainly).
