Can reproduce.

Comment 3 Arjen Hiemstra 2023-12-21 11:15:57 UTC

I can't reproduce this with Plasma 6 Beta 2. Does this still happen?

Yes. If you start plasma-systemmonitor from the command line you can see that it still segfaults after following the steps described above. But for some reason now Dr. Konqi doesn't start. Not sure if that is another bug with Dr. Konqi.

Comment 5 Nate Graham 2025-05-08 15:03:06 UTC

Can still reproduce on git master.
