*** This bug has been marked as a duplicate of bug 408849 ***
It may not be a duplicate. That bug is marked as resolved, but this crash keeps happening on a freshly built version from master.
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
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.
