Crash is in the PostScript/PDF thumbnailer. Please install debug symbols for the kdegraphics-thumbnailers package and post another stacktrace. It would also help if you could identify and attach here the PostScript or PDF file causing the crash.
I installed the mentioned package and now I got this trace: Application: kdeinit5 (kdeinit5), signal: Floating point exception Using host libthread_db library "/lib64/libthread_db.so.1".
