This is the comment for g_dbus_emit_property_changed() /* * Note that when multiple properties for a given object path are changed * in the same mainloop iteration, they will be grouped with the last * property changed.

Debugging found that the three properties "Size" "Transferred" and "complete" were reported at once through the g_dbus_emit_property_changed function, but the "Size" property did not have a value, it appears that there are the following errors "UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb5 in position 0: invalid start byte" in Blueman log. So let the "Size" property use g_dbus_emit_property_changed_full to single emit, if use g_dbus_emit_property_changed（grouped）to emit, there is a possibility that "Size" property value has been freed The following is the issue log dbus-monitor log: signal time=1710900297.140618 sender=:1.50 -> destination=(null) serial=59 path=/org/bluez/obex/server/session4/transfer3;
