Does it also crash when you go to print->properties->advanced?

which printer do you have?

Comment 3 a.key 2018-11-07 11:55:29 UTC 
It does crash when I click on Print->Properties when my default printer is set. With a different printer it doesn't.

I have couple of printers but the default is set to Xerox_WorkCentre-7425 which is a google-cloud-print printer.
Different google-cloud-print enabled (cups) printer doesn't crash when checking properties.
Comment 4 a.key 2018-11-07 12:14:58 UTC 
It actually looks like any KDE application crashes when checking this particular printer's properties.

I tried re-adding the printer using:
sudo python /usr/share/cloudprint-cups/setupcloudprint.py

which gives the same result - crashes.
I also tried adding the printer manually in CUPS - same thing/crashes.
Comment 5 a.key 2018-11-07 12:27:28 UTC 
OK It's probably more to do with the printing subsystem rather than okular. 
I managed to modify the printer's driver in CUPS. Rather than using the default google's driver I chose a manual PPD dedicated for this printer and it seems to have fixed it. So it looks like it's some printer settings that make the KDE printing subsystem crash.

Info provided.
Comment 7 Albert Astals Cid 2018-11-07 21:31:07 UTC 
So not an Okular bug. Please open a bug against Qt printing subsystem.
