See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. Install all current updates 2. Mount a network drive (Mine are from a windows server but others have reported similar issues with other types of network drives) 3. Enable image and video previews in Dolphin 4. Navigate to a folder on the network drive OBSERVED RESULT The folder will not show previews of its contents. EXPECTED RESULT The folder should be showing a preview with 4 images in its thumbnail. SOFTWARE/OS VERSIONS Windows: N/A macOS: N/A Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.24.1 KDE Frameworks Version: 5.91.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION
This problem appears to only be happening for network locations, local storage doesn't have an issue. I've tried everything I can think of from uninstalling dolphin, resetting the settings, clearly my thumbnail cache, etc. The thumbnails for individual files do generate just fine, it's JUST the folder previews that don't.
