Re: Kdemod plasma crash with segfault on logon

Hmm, could be the plasma configurations have gone corrupt.  This be the first thing that I'd try.  For future reference I've built a plasma backup/restore script because this can happen from time to time:

Re: Kdemod plasma crash with segfault on logon

Sorry for bumping an old threat, but thought this might be useful.

Got pretty much same errors after doing a fresh install. Plasma was crashing right after logging to KDE. Turned out it was the networkmanager plasmoid that was causing all this. Removing it solved the problem.

Re: Kdemod plasma crash with segfault on logon

Signaled to kde, they think this currently buggy plasmoid should not be activated by default in arch/kdemod in my case... https://bugs.kde.org/show_bug.cgi?id=232173

Re: Kdemod plasma crash with segfault on logon

I believe the bug is networkmanager not being installed with the plasmoid. Don't forget to make sure networkmanager is installed and add it to your rc.conf - This fixed the issue for me.
