After doing what is in the screenshot, the program crashes

SUMMARY

STEPS TO REPRODUCE

1. Open Trash folder using Dolphin
2. Select any deleted file (not a folder) and drag it to any space area in Trash
3. Dolphin closes unexpectedly and Notifications shows "Move: Failed" (if one does the same thing in a normal folder, a menu with "Copy Here nad Link Here" pops out instead)

OBSERVED RESULT

Dolphin crashes **every single time** after doing so

EXPECTED RESULT

Just show an error message under the directory panel, like dragging a folder in Trash ("Creating folders is not supported with protocol trash.")
