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.
