[SOLVED] Segmentation fault on QT apps

This may be related to https://bbs.archlinux.org/viewtopic.php?id=294803 but I'm not 100% sure.
Running calibre throws segmentation fault. Same happens to qbittorrent but it displays a bit more info:

Re: [SOLVED] Segmentation fault on QT apps

What is /usr/lib/qt6/plugins/wayland-decoration-client/libqadwaitadecorations.so and where did it come from? Can you reproduce the problem with [whatever provides that file] uninstalled?

Mod note: Tentatively moving to AUR Issues.

Re: [SOLVED] Segmentation fault on QT apps

nice catch, wormzy.

It was indeed some issue with

qadwaitadecorations-qt6

from AUR.
Rebuilding it fixed the issue.
