*** This bug has been marked as a duplicate of bug 408849 ***

Comment 2 David 2019-07-03 21:00:13 UTC

It may not be a duplicate.

That bug is marked as resolved, but this crash keeps happening on a freshly built version from master.

Comment 3 Albert Astals Cid 2019-07-03 21:18:56 UTC

No, it does not crash with master

Did you build master yourself?

Did you install to /usr? (hope you didn't)

Because your backtrace says you're using /usr/lib64/qt5/plugins/okularpart.so

So if you did build yourself, you're not running the thing you built. Read the bottom of https://okular.kde.org/download.php

Comment 4 David 2019-07-03 21:38:13 UTC

Ah, yes, okularpart.

The backtrace is with the released version, but after reporting, I built it and installed in ~/.local. But yes, I was loading the okularpart from the system.
Fixing the paths, it works.
