SVGs are renderes to PNG by the mediawiki software. As Internet Explorer can not display transparent areas in these images, he showes them with some sort of default-color (some blue-gray thing). This lookes pretty ugly and prevents the svg-images to be used in articles. (lots of coat of armes and logos are effected by this). (ex.: [[Image:CDU_logo.svg]]) It is possible to define a background color into the png image, which is not shown by modern browsers. In gimp you can choose "Hintergrundfarbe sichern" (german version, should be something like "save background color") when saving as png to do this. White would be a good choice. Result: Forefox, Opera and others show still everything perfect (transparent), Internet Explorer showes a white background. For an example with different images see URL above. Maybe this can be fixed easily within the configuration of the svg renderer.
Confirmed. This bug makes transparent SVGs really ugly (using IE on Windows)! Thus, I changed the importance of this bug.
Note that IE7 (now available as a englis-only beta also working in non-English genuine Windows XP or 2003) will now support alphatransparency in PNG images ; see http://www.microsoft.com/windows/ie/ie7/ie7betaredirect.mspx
The Commons people delete redundant images of PNG, and leave only the SVG - and it makes troubles at the Hebrew Wikipedia, and probably also at many other projects - within Internet Explorer 6 users, and one of the sysops there also requested everyone not to replace the PNG images to the SVG ones (if they are transperent, of course), and uploaded the PNG image to the local server. Now Commons is useless with these images. That's a critical bug for the success of Commons. That's the reason we should fix that bug soon.
Any commons admin doing that should be immediately desysopped.
librsvg 2.14.0 renders its PNGs with a nice white background chunk. Upgrade should resolve this.
Now this bug should be Worksframe, isn't it?

Ok, action=purge can now be used on an image page to force images to rerender. (Be careful about caching; make sure it reloads the new image!)
Thanks for your work, it's a lot better now!
I see the progress for several images, but the crest on <http://de.wikipedia.org/wiki/Bild:Sin_escudo.svg> still looks ugly with IE6 (grey question mark instead of white one)
Use action=purge *on commons*.
