crash log generated by gwenview at some point

SUMMARY
Something is making gwenview crash on open and it's causing many crashes in dolphin when opening a directory with JPG files.

I started to experience this today, even if I don't recall any software upgrade in the last 24 hours.

The crash is related to kioslave5 and probably caused by jpegthumbnail.so which is part of kio5-extras. If you remove that package it will stop generating crashes in dolphin as image preview are disabled, but no luck with making gwenview work.

STEPS TO REPRODUCE
1. Launch gwenview or open dolphin in a directory with JPG files while the file preview is enabled

OBSERVED RESULT
Crash

EXPECTED RESULT
Not a crash
