Arch Linux

After recently updating KDE from 5.9.2-1 to 5.9.3-1 and KDE apps from 16.12.2-1 to 16.12.3-1 [also: linux 4.9.11-1 to 4.10.1-1, glibc 2.24-2 to 2.25-1], plasmashell has been crashing when launching. It does not seem to be a config/cache issue, as removing ~/.config and ~/.cache entirely does not resolve the problem.

I have temporarily mitigated this problem by simply removing libkcupslib.so via pacman -Rdd print-manager.
