GLib-GObject:ERROR: g_type_register_static: assertion failed: (static_quark_type_flags)

Hey, i am running a flutter app on a snap, thats uses this library to communicate with another app over dbus(plugs and slots are connected), the way we are using is

...
void _setupWatchdog() {
  Timer.periodic(const Duration(seconds: 10), (_) {
    var client = DBusClient.system();
    var object = DBusRemoteObject(client, name: 'org.ssi.app.intercom.outdoor.watchdog', path: DBusObjectPath('/org/ssi/app/intercom/outdoor/watchdog'));
    object.callMethod('org.ssi.app.intercom.outdoor.watchdog', 'Feed', []);
    client.close();
  });
}
...

but I am getting below, when I am running the app and it crashes

2024-10-29T13:48:18Z salto-ssi-outdoor.daemon[25697]: Starting app

Any reason that could trigger this error?
Interesting enough, if I get clean build everytime, this issue disappear, I suspect that library itself uses some build time variables to identify itself on dbus or embedded into app.

Thanks

This is a bug in salto-ssi-outdoor.daemon - it looks like it's not handling the D-Bus requests correctly.

[aliihsancengiz]

In daemon, we use dbus only as above snippet,dbus object is sth present on other service which is not a flutter app indeed, so i am curious, why it is working only on clean builds, do you have any clue or tips to debug, i am not a flutter dev @robert-ancell ?

I have the same issue. The only workaround is to use snapcraft clean before creating the new snap.
This is a bit annoying
