Created attachment 19891 [details] Culprit PDF EPS has a "fontbox" (sorry that I don't know the technical term) which is yscaled by a factor of 0, and Poppler sends Cairo a non-invertible matrix resulting in the following Cairo error: cairo context error: invalid matrix (not invertible) The circle in this PDF fails to render in Evince with Poppler+Cairo since in the PostScript the "yscaled 0" fontbox was drawn before the circle. It's like Poppler bails out after encountering this issue.
