Description Ilya Bizyaev 2021-02-18 19:49:23 UTC

SUMMARY
This is better explained in steps:

STEPS TO REPRODUCE
1. Open Dolphin
2. Go to a folder with many small files (e.g. 50 screenshots)
3. Select all fiels and move them e.g. to the parent folder (Ctrl-A, Ctrl-X, Backspace, Ctrl-V)
4. Trash the folder that is now empty (Delete)

OBSERVED RESULT
Dolphin freezes for a minute. So does Latte. So does Firefox if it attempts to send a notification.
Then they all unfreeze, and a job notification is displayed: "Dolphin", indeterminate progress bar. Will only disappear when manually stopped, as no operations are actually happening.

EXPECTED RESULT
The empty folder is deleted without an adventure :D

Can you try to get a stacktrace while it is freezing?
