Pattern image is repeated thousands of times, producing huge output

When source PDF contains multiple references to the same image resource, Poppler output has this image duplicated as many times.
The very original image is the attached slowpptx.pptx (80k). It was converted to pdf using LibreOffice 4.3.1, resulting in attached slowpptx.lo.pdf (35k). Result of
pdftocairo.exe -svg -f 1 -l 1 slowpptx.lo.pdf produces a 1.7M svg (slowpptx.lo.svg.zip), which contains the same image duplicated 1741 times. Same thing happens with pdftohtml.exe -f 1 -l 1 slowpptx.lo.pdf so I assume this is not related to Cairo.
Thanks Dmitry (Internal ref PCC-22530)
