Attachment 42927 [details] is the original file as referred to in the bug.
Attachment 42928 [details] shows the expected outcome
Attachment 42929 [details] shows the actual outcome

As can be seen, one of the C's in the CC logo is missing as it is specified using a use tag.

<svg>
  <path id="lc" d="M ... blah blah ... z" />
  <use id="rc" xlink:href="#lc" transform="translate(5.0)" />
</svg>

Comment 7 Roland Baudin 2011-02-15 12:37:22 UTC 
I have attached two files to illustrate tghe problem with SVG files that contain use element tags.
As can be seen in the odg file, the imported equation is totally garbage...

Is somebody working on this issue? Can we expect it to be solved in the near future?

Another question : would it be difficult for a medium knowledge programmer to implement the use element feature in LibreOffice?

Thanks,
RB

in 3.5.4 the cc logo as well as the latex equation are looking OK.
