Bug ID: 356597
Summary: Plasmashell segmentation faults when confirming or
canceling file deletion with trash widget
Product: plasmashell
Version: 5.5.0
Platform: Archlinux Packages
URL: https://youtu.be/P3936tdm2ws
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: kdeb...@termini.me
CC: bhus...@gmail.com, plasma-b...@kde.org
On both my laptop and desktop dragging a file from a folder view to the trash
widget and confirming or canceling the deletion of the file or folder will
cause plasmashell to segmentation fault and crash. This happened on both
computers after a fresh restart.
Here is a video showing what happens. https://youtu.be/P3936tdm2ws
Disabling the confirmation and dragging a file to the trash widget does not
cause plasmashell to segmentation fault. It does not seem to segmentation
fault when dragging files from dolphin into the widget.
Reproducible: Sometimes
Steps to Reproduce:
Steps to reproduce:
1. Check in dolphin under the menu settings menu, configure dolphin, general,
confirmation "moving files or folder to trash" is checked.
2. Add a trash widget to your desktop
3. make sure you have your desktop in folder view
4. Drag a file to the trash
5. Confirm or cancel the deletion ( I suggest cancel as it does not always
crash)
Actual Results:
It may crash plasma and it will restart, if it does not try again it happens
every other time or so. I also noticed it seems to happen more when the widget
and folder view are on the same display although this may just be me.
Expected Results:
Plasmashell should not segmentation fault.
