            Bug ID: 468673
           Summary: Memory leak when pasting files in administrato mode
    Classification: Applications
           Product: dolphin
           Version: 22.12.3
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org

  Target Milestone: ---

I wanted to get the new Partition Manager icon so badly that I downloaded it
from gitlab, and went to the specified path:  /usr/share/icons/breeze/apps/48/
which I needed to open in admin mode to be able to paste the icon there. Less
than 30 seconds after pasting it, RAM usage skyrocketed and computer froze.


STEPS TO REPRODUCE

1. Right click a file and select "copy" (you can try with a svg icon, like I
did)
2. Open a protected path like /usr/share/icons/
3. Right click in an empty space and select open as administrator
4. Paste the icon/file, you will be prompted to put your password
5. As soon as the copy operation finishes, memory usage starts to skyrocked
leading to a computer lockup

OBSERVED RESULT

Computer totally frozen because the system runs out of RAM

EXPECTED RESULT

It shouldn't leak memory so much and so fast.
