Sentry Crash Report:

Description andy_90254 2014-01-15 21:54:05 UTC 
Application: plasma-desktop (4.11.3)
KDE Platform Version: 4.12.0
Qt Version: 4.8.2
Operating System: Linux 3.2.0-58-generic-pae i686
Distribution: Ubuntu 12.04.4 LTS

-- Information about the crash:
- What I was doing when the application crashed: I was typing in google spreadsheet when my softphone (jitsi) rang.  I switched virtual desktops to answer it.  Then, while still on the phone I opened NixNote which was running in the tray.  Within a few seconds, plasma crashed.

This is not the first time this, or other programs have crashed.  What may (but shouldn't) be part of the issue:  I installed the system using debootstrap and the mini iso.  I then installed kde-desktop and built up from there.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".

Comment 1 Nate Graham 2018-06-08 18:55:05 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
