SVG backend - resulting files invalid?

[Daniel Johnson]

Hi all --

I have both Lilypond 2.6.3 and 2.7.7 installed.  I've been trying to 
generate SVG files (using both versions) using the following invocation:

lilypond --backend=svg --formats=svg my_file_name.ly

my_file_name.ly is a multiple-page valid Lilypond file which worked 
great using the PDF backend.  I tried opening the resulting 
my_file_name.svg in various apps, with the following results:

- Inkscape, Karbon14 and KWord just draw an empty page. (Inkscape 
0.42.2, KOffice 1.4.1)
- Firefox (compiled with MozSVG support) hangs (Firefox 1.0.6)
- Konqueror and rsvg-view render the file with all pages printed on top 
of each other, very very tiny. (KDE 2.4.1, rsvg-view 2.9.5)
- Abiword renders the file with all pages overlapping, at extremely 
fuzzy resolution; stems are not correctly aligned, and certain 
Emmentaler glyphs are wrong (such as clefs) (Abiword 2.2.8)

I don't have OpenOffice installed, so I couldn't test how it reacts to 
Lily's SVG.

I tried the above steps with two different files which produce correct 
PDF output.  Both files are multiple pages.  When I tried this with a 
single-page Lily document, I got the following results:

- Inkscape opened the file correctly
- rsvg-view and Konqueror opened the file correctly but rendered it very 
very tiny
- Firefox showed all characters on top of one another
- Karbon14 only showed staff-lines, measures, stems and ledger-lines; 
all character data was missing.
- Abiword had the same problems as above, except of course no 
overlapping pages
- KWord showed correct glyphs for accidentals, but incorrect glyphs for 
noteheads and clefs; most vertical lines were missing.

Any hints on how to get Lily to behave with SVG?
