Description Antti Savolainen 2023-12-21 00:24:29 UTC

SUMMARY
Demonstrative video: https://www.youtube.com/watch?v=AUxgQcOxQuU
I used yt-dlp to download a long stream which gave me a corrupted file linked here. https://drive.google.com/file/d/1ttPTzrJbEhoCSSJZpg86nhDQHigv9TSl/view?usp=drive_link. Whenever I hover over the file, Dolphin freezes. Furthermore, if I try to graphically copy the file, Dolphin shows an error message that the file doesn't exist


STEPS TO REPRODUCE
1. Download the corrupted m4a file
2. Hover over it

OBSERVED RESULT
Dolphin freezes for about 5 seconds

EXPECTED RESULT
Dolphin should allow me to manage the file like normal

I can reproduce similar behavior. Upon rising edge of the file being onscreen, and while the file is hovered over, there is a 100% 1-core CPU usage from /usr/libexec/kf6/kioworker. Also, when viewing the Properties for it, dolphin freezes for several seconds.
