Sentry Crash Report:

Description Juan Victor May da Rosa 2016-03-17 01:38:25 UTC 
Application: plasma-desktop (4.11.20)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 3.16.7-35-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

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

I was trying to add the Folder widget on the lower panel, when I unintentionally moved the icon above the activity manager button (I think this is the name). It always crashes when I try to do this, or even when I try to put the widget between the task manager buttons (where stay the buttons for the windows I've opened). Sorry for my bad english (if it is).

- Custom settings of the application:

When using the default desktop activity on the KDE.

-- Backtrace:
Application: Shell da área de trabalho do Plasma (plasma-desktop), signal: Segmentation fault

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
