Allow parallel installation of app bundles
With the help of @alatiera yesterday, I have finally been able to finish it yesterday. Much appreciated! Everything seems to works fine.
The application menu was not visible because the
resource_base_path was changed to
/org/gnome/MusicDevel as it is based on the
application_id by default. So, I changed this property in the constructor:
self.props.resource_base_path = "/org/gnome/Music"
