Files saved with blur seem to render correctly in Batik though not in Firefox (which does not support filters yet).
Just for the information, files with blur render perfectly in Opera 9.x (it supports filters)
Thanks! Molumen

Whoops, old info. Running inkscape in debugger, I just struck gold and found the reason for this problem. (a rather stupid one, too, so I won't go into further detail) Now fixed in SVN.
Thanks! Finally the blur is usable with UI - please everyone check it out (it's in the Fill & Stroke dialog at bottom).

There are still things to be done. Here's what I have proposed, please everyone feel free to discuss and add to the list:
- There is still some banding happening when I scroll the window with
a blurred object so it scrolls in from beyond the screen. There's perhaps some error in determining how much the buffer needs to be enlarged so that the rendering strips tile up seamlessly.
- When nothing selected, the blur slider should be grayed out, as is
the Master opacity control.
- I think it makes sense to set and display blur radius in % of the
current object size (the diagonal of its bbox). Otherwise it's almost useless for small objects - a 0.01 increment is too much for them. I think 50% is a reasonable maximum value - any stronger blur just makes little difference visually.
- If the radius set by the user is bigger than 10% which is the SVG
standard filter area margin, you need to also set the corresponding larger margin, so that blur is never cut off.
- Speaking of cleaning up console output: I see lots of
(inkscape:7289): GLib-GObject-WARNING **: invalid cast from `(null)' to `SPGaussianBlur'
on the console.
- While not directly related to the slider, we need to make it so that
the blur radius is scaled proportionally when the object is scaled. This can be coded similar to the way stroke width is now treated. Later we can add another button in the row of "scale with object" buttons on Selector controls bar for the blur (now it has buttons for stroke width, rounded rect corners, gradients and patterns). (I think I'll try to do this myself because I know this code.)
