Description Alex 2016-01-29 19:05:10 UTC 
LibreOffice Writer seems to retain embedded images in .wmf format by default when going from .doc to .docx. However, libwmf is unmaintained these days, leading to issue opening them in imagemagick, and often necessitating a second LibreOffice call to convert the .wmf images (leading to listener headaches, because LibreOffice's code base appears not to use libwmf and actually works, albeit with a lot more overhead than imagemagick) when trying to script this all headlessly.

I'm not sure if it technically violates the .docx standard but it might not be a bad idea to just transform them all to .png by default when the document itself is converted in order to avoid this.

I guess the issue is in imagemagick and not in LibreOffice. Besides, we don't plan to convert images to .png as export time as it might bring other downsides.
Closing as RESOLVED WONTFIX
