New crash information added by DrKonqi

plasma-desktop (0.4) on KDE Platform 4.9.2 using Qt 4.8.3

- What I was doing when the application crashed:
Login to opendesktop.

- Unusual behavior I noticed:
I had just registered for the site and was logged on to the website. After the crash occurred I saw the api.opendesktop.org had sent me a popup that someone was trying to make me logon, while it was not necessary. I could just click this was ok.

However, this may or may not have had influence on the crash.

Comment 13 Nate Graham 2018-06-08 18:51:58 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
