SUMMARY
Some KDE Flatpak apps print a lot of
  WARNING: KServiceTypeTrader: serviceType "ThumbCreator" not found
messages in the console. I noticed this with Skrooge, someone else noticed it with the vidcutter flatpak app (https://github.com/ozmartian/vidcutter/issues/205)

STEPS TO REPRODUCE
1. flatpak run org.kde.skrooge
2. File > Import > Import...
3. Navigate around the local filesystem in the open dialog.

OBSERVED RESULT
Lots of these messages in terminal.

EXPECTED RESULT
??

SOFTWARE/OS VERSIONS

Linux/KDE Plasma: 
(available in About System)
KDE Plasma Version: 5.16.14
KDE Frameworks Version: 5.62.0
Qt Version: Qt 5.12.5 (built against 5.12.5), xcb back-end

ADDITIONAL INFORMATION

`flatpak run org.kde.kate` only prints this warning once and seems to show thumbnails OK.
The Fedora skrooge package does not display these warning messages.
I don't know that the financial file types that Skrooge handles have thumbnails, unlike e.g. images. I see file icons for them in the File Open dialog.

I got this type of error with dolphin on openSUSE Leap 15.2 (KDE Frameworks 5.71.0, Qt 5.12.7) after searching for an issue why image preview did not work (No image preview types in settings  (Settings/General/Preview)

For dolphin the issue has been solved by installing the kio-extras5 package.
