What happened?

After locking my GNOME desktop, VirtualBox segfaults. Looking at the logs, it looks like something went wrong with QAccessibleWidget, hence why I selected the GUI component.

I'm using the default package for VirtualBox, I'm using Wayland display, and my kernel version is "Linux 6.19.11-arch1-1". I may be able to provide more information on request. I don't know how useful the stack traces below will be: let me know if I need to build VirtualBox from source, to see exactly which symbols were involved.

Here's the stack traces:

Process 13059 (VirtualBox) of user 1000 dumped core.
