This is supposed to be a bug in Qt, but it still seems to be an issue in Qt 4.8.4. Where is the upstream bug, and when is it supposed to be fixed?

New crash information added by DrKonqi

plasma-desktop (4.12.2) on KDE Platform 4.12.3 using Qt 4.8.6

- What I was doing when the application crashed:

I hit Ctrl+Q in Choqok and then opened a menu option in the menubar plasmoid in a panel. The desktop froze; then crashed.

Comment 19 Nate Graham 2018-06-08 19:08:30 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
