Description Frank 2013-10-17 15:30:36 UTC 
Application: plasma-desktop (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.5
Operating System: Linux 3.11.5-32.ga012288-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I started to add system load viewer widget positiong it striving left and right over the bottom taskbar then the crash was reproducable every time even though the left mouse button wasn't released because the intended final position wasn't fixed.
Tumbleweed

The crash can be reproduced every time.

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

plasma-desktop (4.11.8) on KDE Platform 4.13.0 using Qt 4.8.6

- What I was doing when the application crashed:

I was adding the fast launcher object to the bottom panel.

I didn't do anything fancy, nor I had anything particular going on. I simply:

 - Right clicked the panel to get the context menu
 - Selected Add objects...
 - Selected the fast launcher ("Avvio rapido" in the Italian interface)
 - Dragged it on the panel in order to add it.

Suddenly the panel disappeared and after some seconds the crash was reported and the panel restarted.

This already happened more then once.

Comment 31 kailoran+kde 2014-12-04 08:22:07 UTC 
This seems to crash repeatedly when I drag and drop the new widget over an existing  task manager widget instance on the panel, and does not crash when I drop it on the side over/next to an existing clock widget. When the crash happens it's even befor I release the mouse button, i.e. just dragging the new widget over causes the crash for me (still repeatable).
Comment 32 Jaroslav Reznik 2014-12-04 08:54:06 UTC 
I'm able to reproduce by dragging new widget to panel over task manager widget but only when added through right click, panel options, add widget and dragging some widget to panel. Does not happen when using add widget from the panel bar.

Comment 52 Nate Graham 2018-06-08 18:33:43 UTC 
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
