While opening a PDF with evince (a large, custom one that opened cleanly on
former
versions of evince, and still opens cleanly in xpdf or okular, even if okular
needs too much memory to zoom), I get a SIGSEGV.
After installing debug info, here is what I receive:

The PDF can be made publicly available.
pdftoppm from poppler-utils also does not fail to convert the file to ppm when
asked.
What can I do to help?
