Sorry, it seems it's the Okular's bug. I'll send the report appropriately.
Comment 3 Elvis Angelaccio 2019-06-17 20:54:37 UTC 
No need to, I changed the product of this one. :)

I'm sorry again. It seems I've already sent one :). Here is a link (you might want to mark it as duplicate): https://bugs.kde.org/show_bug.cgi?id=408851

The file that causes this crash.
Comment 6 Vasyl Teliman 2019-06-17 21:08:52 UTC 
By the way, I've failed to mention here that it'd worked OK until I've decided to update KDE to 5.16.0
Comment 7 Wolfgang Bauer 2019-06-19 11:59:52 UTC 
I think it's caused by this Qt bug:
https://bugreports.qt.io/browse/QTBUG-73730

Should be fixed in the latest 5.12.4.

PS: I can indeed open the attached file just fine here with Qt 5.12.4 (and ark/okular 19.04.2).
