Comment 3 for bug 823274

Could you provide more information about the PDF file?
- Which application was used to create it originally?
- Did you round-trip edit the PDF file in Inkscape? (open PDF, edit, save as PDF)
- Could you possibly attach an unedited version of the PDF file (without having been edited and resaved in Inkscape)?
