Description Tor Bellino 2014-01-20 00:37:04 UTC

KDE Platform Version: 4.11.5
Qt Version: 4.8.4
Operating System: Linux 3.11.0-15-lowlatency x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:

I had a few applications open. I was changing the order in which they appear in the task manager, when plasma crashed and reset itself.

The crash does not seem to be reproducible.

Comment 2 Nate Graham 2018-06-08 19:03:58 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 is already 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
