Description rizsilverthorn 2012-11-22 18:23:47 UTC

Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.2
Qt Version: 4.8.3
Operating System: Linux 3.5.0-18-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:

Attempting to add Fuzzy Clock Widget to the default panel at the bottom of the screen. Opened Add Widgets, scrolled to Fuzzy Clock, dragged Fuzzy Clock to panel. Noticed after releasing mouse button that the icon for Fuzzy Clock had frozen at the bottom of the widget bar. Mouse pointer was moving freely.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault

Adding a plasmoid to the default panel by drag'n'drop from the "add vidgets"panel straight to the default panel leeds to crash - you need to drop it on the "desktop" 1st

Hello!

This bug report was filed for KDE Plasma 4, which reached end-of-support status in August 2015. KDE Plasma 5's desktop shell has been almost completely rewritten for better performance and usability, so it is likely that this bug has already been resolved in Plasma 5.

Accordingly, we hope you understand why we must close this bug report. If the issue described  here is still present in KDE Plasma 5.12 or later, please feel free to open a new ticket in the "plasmashell" product after reading https://community.kde.org/Get_Involved/Bug_Reporting

If you would like to get involved in KDE's bug triaging effort so that future mass bug closes like this are less likely, please read https://community.kde.org/Get_Involved#Bug_Triaging

Thanks for your understanding!

Nate Graham
