Bug ID: 450663
Summary: Deleting Panel with Panel Spacers on it crashes Plasma
in PanelSpacer::containmentGraphicObject()
Product: plasmashell
Version: master
Platform: Other
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: Panel Spacer
Assignee: plasma-b...@kde.org
Reporter: n...@kde.org
Target Milestone: 1.0
Steps to reproduce
1. Create a new empty panel
2. Put an applet on it, and a Panel Spacer applet on each side
3. Delete the panel
4. Click the "Close" button on the "Undo deleting this panel?" notification
(this will actually perform the deletion in the background)
Plasma then crashes:
