SUMMARY *** Upon opening '/home/Pictures/test' kioslave5 goes crazy and uses 100% CPU. Doesn't want to stop. After a few minutes I gave up and closed Dolphin. *** STEPS TO REPRODUCE 1. On a fresh (Fedora 38) install rsync photo files* to your /home/Pictures/test (no thumbnails cache yet, kimageformats installed). 2. Press ctrl+E and go to Pictures/test where you had put the photo files * just three rows of the following photo type files: jp2, png, tiff, webp, avif, cr2, xmp, jpg, raf, 3fr, dng, mrw, nef, orf, srw, rw2, x3f, arw. OBSERVED RESULT 3. Kioslave5 uses 100% CPU and doesn't want to give up. (I gave up after a few min) EXPECTED RESULT Fix kioslave5 not to use 100% CPU. SOFTWARE/OS VERSIONS Operating System: Fedoara Linux 38 KDE Plasma Version: 5.27.5 KDE Frameworks Version: 5.107.0 Qt Version: 5.15.10 X11 ADDITIONAL INFORMATION kimageformats installed (so are ffmpegthumbs for videos) x11 (not wayland) mesa-freeworld (uncastrated) obviously intel-media vaapi
Hello, try to evaluate which file is causing the high CPU utilization and send us a test file. Developers need the test file(s) so they can reliably reproduce the problem and/or confirm when it is fixed.
Have same problem about several years on Fedora 35-38. If I am downloading some big files using qBittorrent and the Dolphin is opened at the target files directory, the kioslave5 creates several processes with extremely high CPU usage (load average > 1). It does not stop in 5 or 15 minutes and quickly drain my battery

Interestingly, entering back into the directory did not cause it to raise again. The directory is the destination for qBittorrent v4.6.3 (flatpak) while getting https://rutracker.org/forum/viewtopic.php?t=5662750 at approx. 2-4 MiB/s
