rsvg-convert issue with libxml 2.9.5

Hi,

we have svg file which used to work with libxml 2.9.4. Now with 2.9.5 
(plus latest few commits) I see:

$ rsvg-convert test.svg > test.png
Error reading SVG:Error domain 1 code 4 on line 1 column 1 of 
file:///builds/psumbera/userland-libxml2-2.9.5/components/libxml2/build/prototype/test.svg: 
Start tag expected, '<' not found


$ head -13 test2.svg
<?xml version="1.0" encoding="utf-8"?>
<!-- Generator: Adobe Illustrator 13.0.2, SVG Export Plug-In . SVG

When I modify the file little bit it seems to work again:

$ head -4 test2.svg
<?xml version="1.0" encoding="utf-8"?>
<!-- Generator: Adobe Illustrator 13.0.2, SVG Export Plug-In . SVG 
Version: 6.00 Build 14948)  -->
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.0//EN" 
"http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd" >
<svg version="1.0"

Any idea what is wrong?

Thank you,

Petr
