Description Patrick Silva 2022-05-29 14:38:27 UTC 
SUMMARY
I can't reproduce this bug consistently, but it occurs often after the steps below.

STEPS TO REPRODUCE
1. have a folder containing many files - I can reproduce with a folder containing 2036 jpg files
2. select all files in your folder, right-click on any selected file, choose 'Rename...'
3. type a new name and press enter
4. when mass renaming is completed, undo it by pressing ctrl+z
5. when mass renaming is undone, Plasma shows a notification saying 'Moving (Finished)'.
Close Dolphin while this notification is visible.

OBSERVED RESULT
Dolphin gets stuck in the memory for several minutes - from 3 up to 8 minutes in my tests - and causes high cpu usage - ~25% on my system - until it finally exits.

EXPECTED RESULT
Dolphin process should exit immediately when Dolphin is closed
