[Bug 2022878] [NEW] Kubuntu KDE Plasma systemsettings crashes with "corrupted double-linked list" when proprietary AMD video drivers installed

[Daniel Ayers]

Public bug reported:


Fairly recent fresh install of Kubuntu 22.04.2LTS on AMD Ryzen 9 5950X with 128Gb RAM, Radeon RX 6700/6700 XT / 6800M video card.

$ lsb_release -rd

Originally ran the system using the bundled (open source) AMD video drivers.  No problems.

Recently installed the proprietary AMD video drivers to get OpenGL
support:

$ dkms status
amdgpu/5.18.13-1577590.22.04, 5.19.0-43-generic, x86_64: installed

On first boot after installing the proprietary AMD drivers the system
hangs at the Plasma splash screen that appears after logging in.  That
appears to have been caused by a malformed udev rules file ("==" instead
of "=").  Fixed that, long pause goes away.  Appears unrelated to this
issue.

Since installation of proprietary AMD drivers, I can open systemsettings
OK, and I can click "Startup and Shutdown" OK, but as soon as I click
"Autostart" systemsettings crashes with 100% reproducability.

stdout/stderr from the process is as follows:

Also see this upstream KDE bug report re the same problem on Kubuntu (reported by a different person, not me).  Upstream declined to investigate due to the KDE Plasma version in Kubuntu being too old:
