            Bug ID: 424052
           Summary: Dragging a deleted file in Trash folder causes a crash
           Product: dolphin
           Version: 17.12.3
          Platform: Kubuntu Packages
                OS: Linux
            Status: REPORTED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org
          Reporter: yongzhen.ren.0423 at gmail.com
                CC: kfm-devel at kde.org
  Target Milestone: ---

Created attachment 130018
  --> https://bugs.kde.org/attachment.cgi?id=130018&action=edit
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.")
