KDE Frameworks Version: 5.67.0
Qt Version: 5.15.0
Kernel: 5.5.7

ADDITIONAL INFORMATION
The crash is always happening in okularparts.so (See backtrace below). This
issue started about 2 weeks ago. I thereafter compiled okular and replace my
compiled version of okularparts.so with the packaged one and everything worked
ok again. After a subsequent update via pacman -Su i noticed that the problem
is back! causing to to again replace okularparts.so with my own compiled
version.

backtrace:

Application: Okular (okular), signal: Bus error
