Issue with canberra-gtk after upgrading to ubuntu 23.04

Hi all,
just upgraded from ubuntu 22.10 to 23.04. I have a xojo program that when reading a file returns this error:

ERROR:canberra-gtk-module.c:874:on_object_disposed: assertion failed: (d->object == NULL || d->object->ref_count > 1)
Bail out! ERROR:canberra-gtk-module.c:874:on_object_disposed: assertion failed: (d->object == NULL || d->object->ref_count > 1)

Canberra is updated (libcanberra-gtk-module is already the newest version (0.30-10ubuntu4).

Everything was fine with the previous ubuntu version.
Any idea?
thanks in advance
Stefano

Just an update. The problem is caused by “SavefileDialog” and “OpenFileDialog” when using the Xorg display server in Ubuntu 23.04. For Wayland the problem does not occur
