fatal PDF document

Comment 2 Yuri Chornoivan 2019-01-08 14:28:50 UTC

Works fine, no crashes in Okular 1.6.0, KDE Frameworks 5.53.0, Qt 5.12.0, Poppler 0.72 (64-bits).

Comment 3 Oliver Sander 2019-01-08 14:31:55 UTC

The backtrace looks like the crash is in poppler.  Can you try pdftocairo and see if that triggers the crash?  Can you try a newer version of poppler?

Comment 4 RJVB 2019-01-08 19:42:38 UTC

You're right, it was a poppler issue. An upgrade to poppler 0.73.0 (without changing anything else) fixed it for me.
