            Bug ID: 454577
           Summary: Dolphin gets stuck in the memory and causes high cpu
                    usage when closed immediately after undoing mass
                    renaming
           Product: dolphin
           Version: unspecified
          Platform: Neon Packages
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR

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
