Pandoc version 1.11.1
libreoffice 4.1.3.2
on Debian testing (jessie)

libreoffice is unable to open odt files produced by pandoc if they contain more than 1 image.

Test case:

echo '<?xml version="1.0" encoding="utf-8"?>
<svg xmlns="http://www.w3.org/2000/svg" width="800" height="600" version="1.1"/>' >img1.svg
echo '![](img1.svg)
![](img1.svg)' >test.md
pandoc -o test.odt test.md
soffice test.odt

libreoffice opens and presents a dialog box reading:

Read-Error.
Error reading file

The issue disappears if the image included only once.

The issue is still present when:

• Two different images are included rather than the same one twice
• The image is in PNG format instead of SVG.

I have not yet tested with Pandoc 1.12.1 as I am having difficulty building it.

I do not know if this is technically a libreoffice or a pandoc issue, either way I think it's important that pandoc produces ODTs that libreoffice can open as that is what the majority of people will be using to open the ODTs.
