Description Frans Englich 2005-04-19 21:53:07 UTC
Version:            (using KDE Devel)
Installed from:    Compiled sources
OS:                Linux

When attempting to open:
http://openclipart.org/incoming/lightbulb-notlit_benji_p_01.svg

or any other SVG files listed in the right column at openclipart.org, I get:

XML parsing error
fatal parsing error: the document is not in the correct file format in line 20, column 46
   xmlns:xlink="http://www.w3.org/1999/xlink">
                                             ^
To my knowledge I have nothing installed which should perform SVG rendering, but no matter how Konqueror decides to handle it, it shouldn't be flagged as a parser error of any kind, since according to my judgment this is well-formed XML.

File will be attached for persistence.


Cheers,

       Frans

Comment 2 Maksim Orlovich 2006-03-02 01:40:37 UTC
It doesn't like the sodipodi:version before the xmlns declaration. 
Comment 3 Maksim Orlovich 2006-09-23 21:03:29 UTC
SVN commit 587710 by orlovich:

Workaround a bug in QXML where it doesn't properly resolve namespace of attrs
preceeding the xmlns declaration. Makes photos on new.photos.yahoo.com show up 
(though page is still very buggy) and fixes #104236
