Description ElectronicsArchive 2022-04-27 22:20:41 UTC 
SUMMARY
After I upgraded to the newest LTS version of Ubuntu / Kubuntu (22.04),
( Wiped the system, new install )
Dolphin hasn't been showing image thumbnails anymore.

I checked the '~/.xsession-errors' and only found this non-descriptive error:
'org.kde.dolphin: Failed to generate hover sequence preview #1 for file "<path>" (attempt <attempt>/3)'
( Many of times, for any images I hovered over )

STEPS TO REPRODUCE
1. Open a folder containing images 

OBSERVED RESULT
- PNG, WEBP, WEBM, JPG, GIF files have no thumbnails

EXPECTED RESULT
Image files have thumbnails

Linux/KDE Plasma: Kubuntu 22.04  / 5.24.4
(available in About System)
KDE Plasma Version: 5.24.4

Is this in an NTFS volume?

No, ext4.

Out of desperation I decided to reinstall my system once again..
At least it worked out, Dolphin now seems to work.

Nonetheless the error message isn't exactly great.
It would be lovely to get a reason for it failing.

Also not having it be disabled anywhere in the UI is unfortunate.

If it's working now, I don't know if there's any way we can diagnose the original problem, unfortunately.
