Bug#1081957: libgtk-4-bin: GTK applications crash on startup

[Zoltán]

Package: libgtk-4-bin
Version: 4.16.1+ds-2
Severity: important

Dear Maintainer,

Since installing the new version on sid gtk4 applications crash on
startup with SIGSEGV.

The crash seems to occur with the vulkan renderer, disabling it with
GDK_DISABLE=vulkan things run fine.

I'm running a kde desktop on wayland (kwin-wayland 4:5.27.11-2)
on AMD with mesa-vulkan-drivers 24.2.2-1

Example partial backtrace:

Thread 1 "zenity" received signal SIGSEGV, Segmentation fault.
