If you switch from Kickoff to Simple Menu then switch back to Kickoff, the whole Plasma desktop crashes.

Can't reproduce. Do you have any other operation after switching back to Kickoff? The backtrace log is not helpful. Please download debug symbols and produce a new backtrace.

Please download debug symbols and produce > a new backtrace. Arch based distros don't ship debug symbols and to install them you have to wreak your stable installation (I'm currently on Manjaro stable branch) by pulling source code of all current plasma git packages and changing some compiler arguments then compiling them. I attached a video showing the complete scenario. And bellow you find the output printed on terminal when I launch plasmashell from it.

Then i suggest you switch to a distro which actually enables upstream developers to debug crashes.
(In reply to Kai Uwe Broulik from comment #5) > Then i suggest you switch to a distro which actually enables upstream > developers to debug crashes. No, nothing beats Manjaro performance and stability.
There is nothing we can do with this bug report of there are no debug symbols. I am sorry.
