I usually have 10-20 Okular windows open at the same time. When I close them simultaneously by right clicking on the collapsed Okular entry in the task bar and selecting "Close", plasma freezes sometimes. I then have to kill it and restart it to get back to a working system. The error seems to occur mostly after starting the computer with a few restored Okular windows that were opened by the browser and that could not be restored properly (temp-file no longer available after boot, etc.)
after restarting of computer - multiple Okular errors with 'could not open...' dialogs occurred - tried open pdf files in Firefox with external (Okular) viewer with Plasma session restore enabled also tried to suspend system - group of Okular instances closing normally after system waked up okular 17.12.2-1 Plasma: 5.12.2 Apps: 17.12.2 Frameworks: 5.43.0 Qt: 5.10.1 Kernel: 4.14.20-2-MANJARO OS: Netrunner Rolling
Was able to reproduce Plasma freezing upon closing of multiple instances of Okular spontaneously - was playing with Task Manager's 'Show only task from the current desktop/activity' settings - disabled desktop/enabled activity checkbox and then tried to close Okular and Plasma became frozen
