SUMMARY
If I put large USB medium into my computer and open in Dolphin, some background process starts and it prevents us from un-mounting device.


STEPS TO REPRODUCE
1. Put large USB medium with a lot of files into computer and open it in Dolphin
2. After few time (seconds or minute) try umount/eject it

OBSERVED RESULT
Dolphin says: 
One or more files in this device are opened in program "dolphintvmYuY.9.slave-socket". (This is free translation from Lithuanian into English – not exact wording)
I see active process: /usr/lib64/qt5/plugins/kf5/kio/thumbnail.so
Device is still mounted.

EXPECTED RESULT
Any low priority background process (e.g. thumbnail.so) must be killed immediately.
Device should be umounted.

SOFTWARE/OS VERSIONS
Operating System: openSUSE Leap 15.2
KDE Plasma Version: 5.18.5
KDE Frameworks Version: 5.71.0
Qt Version: 5.12.7
Kernel Version: 5.3.18-lp152.29-default
OS Type: 64-bit

ADDITIONAL INFORMATION
Tested USB medium has 64GB, is near full, contains ~5000 files and ~400 directories.

Workaround: After killing thumbnail.so process manually, I can un-mount USB-stick successfully via Dolphin or KDE Plasma system tray.
