[Linux] StatusNotifierItem service is not introspectable on dbus
I've submitted this as a bug report but I'm posting here too as I've no idea how support on Discord works.
Since upgrading to version 0.0.26, icons are no longer appearing in my tray. Having looked into this, it seems that 0.0.26 has changed the implementation of the StatusNotifierItem specification. The issue with the current implementation is that the service is not introspectable by clients so they cannot determine what interfaces are provided.
In version 0.0.25

Ah. So that last command fails because you're not implementing the spec correctly. You don't provide an "IconName" property.
