"Rubbish" code in svg. Images, fonts

Tested on Windows XP, Inkscape 0.48.5 and trunk rev. 13836.

a) Not reproduced. The layer and all its content are correctly removed from the file.
b) I'm not sure if it's a bug or a feature. Keeping text and font data is very useful if someone needs to modify the converted text. It is then possible to use the same original font and text attributes to be sure the new path is consistent with the old one.

Could you please give details on your OS and Inkscape version, and attach an example SVG file showing the image element?

Sorry it took me so long to answer.
a) I have tryed to reproduce the "bug" and I was not able.
I found a file that gave me problems. I see the images are <g display="none">
I can't recall my workflow but I guess:
 - I was changing the opacity of the images to 0, then deleting the layer *I thought* those images were in.
 - Optimized svg through external service and kept the empty image tags

So -> not a bug (other than me :( )

b) If including the font properties is a function (and I think you're right when saying it helps to add a text similar to the converted to path), then:

 - It wouldn't be helpful to add the font name?
 - It wouldn't be nice to get rid of this info in a "optimized" svg?

(I changed it to opinion as we can consider these not bugs)

Proposing to link as duplicate to bug #168720 instead (if that's the one remaining issue of this report).
