Commit 7190c5024d introduced the usage of new GObject define macros with private. However as the conversion hasn't been done for abstract types (G_DEFINE_ABSTRACT_TYPE) and the addition of the private classes for the abstract types has been removed as part of the commit, crashes can be seen in Apps consuming libvirt-glib, as this one from GNOME Boxes: Thread 1 "gnome-boxes" received signal SIGSEGV, Segmentation fault. 0x00007ffff7ef2b35 in g_type_check_instance_is_fundamentally_a () from /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0 (gdb) bt #0 0x00007ffff7ef2b35 in g_type_check_instance_is_fundamentally_a () from /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0 #1 0x00007ffff7ed2e75 in g_object_unref () from /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0 #2 0x00007ffff6ef094e in gvir_domain_device_set_property (object=0x555556680950, prop_id=2, value=0x7fffffffcbe0, pspec=0x555556772540) at libvirt-gobject-domain-device.c:89 #3 0x00007ffff7ed3b19 in ??
