As I said in launchpad, In Ubuntu's LibreOffice, one can also reproduce this issue with KDE's Okular, and also by exporting to EPS first, and then using epstopdf to obtain a PDF file. So it seems to be something in the way LibreOffice generates the plot (EPS, PDF), that is not visible in EPS or some PDF viewers, but it is shown (or triggers a bug) in other PDF viewers.
It can be observed by exporting to EPS a simple arrow. Unfortunately, my knowledge of EPS is not enough to understand what is wrong in the EPS generated.
