Comment 7 for bug 2027571

it seems to be an issue with gtk 4.

$ sudo apt install gtk-4-examples
$ gtk4-demo-application

the demo app gives me the same error.

the binary is dynamically linked to
 /lib/x86_64-linux-gnu/libgtk-4.so.1

which itself point to
/lib/x86_64-linux-gnu/libgtk-4.so.1.600.6
