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 SOFTWARE/OS VERSIONS Operating System: openSUSE Leap 15.2 KDE Plasma Version: 5.21.0 KDE Frameworks Version: 5.79.0 Qt Version: 5.15.2
Can you try to get a stacktrace while it is freezing?
