When opening the following PDF in Evince (https://dl.ubnt.com/guides/edgemax/EdgeSwitch_ES-48_QSG.pdf), it crashes with the following backtrace:

Upstream seems to have fixed this already:

The following debdiff fixes the issue.

And for SRU:

[Impact]

Evince crashes while opening some PDF's.

[Test Case]

Open the PDF https://dl.ubnt.com/guides/edgemax/EdgeSwitch_ES-48_QSG.pdf and scroll to page 7 for example.
This crashes every time.

[Regression Potential]

Should be safe. Patch also got included upstream.

[Jean-Louis Dupond (dupondje)]

The version in Yakkety already includes this patch.
https://cgit.freedesktop.org/poppler/poppler/commit/?id=7d8dfb09d2b9d69d4e80838ce58fdbd091bce7ec

Was committed pre 0.43.
