Arch Linux

Description:
When using pdflatex to compile a tex file which includes a pdf file that itself has embedded fonts,
pdflatex crashes with the error:

"Internal Error (0): Call to Object where the object was type 5, not the expected type 8"

This error has also been reported to poppler here:
https://bugs.freedesktop.org/show_bug.cgi?id=102952

where multiple people confirm that downgrading to poppler 0.57 fixes the issue.
One of the folks on the thread suggested that this patch might be the issue:
https://git.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/texlive-bin&id=9d93b64063f7d98568d4f029453c7edf5597a7b4

I've attached a MWE including a pdf file that triggers the issue (generated today with inkscape) and a
.tex file that includes it and when compiled results in the error.

When exporting a inkscape drawing as a PDF, if you choose to convert text to paths, there is no issue.
Interestingly, when including other PDFs that have embedded text (like those produced by pdflatex) there is also
no issue.
