[Libosinfo] Errors on import

[Loranz Steve]

Hello,

I previously emailed the list about unsuccessfully using get_install_script() on an instance of Db. I thought I would try a different route and try instantiating an empty InstallScript and using generate, supplying the OS, an InstallConfig, and a Cancellable object.

I'm seeing the following behavior depending on the order of the imports:

If I ignore the warning from importing Cancellable after Libosinfo, I get the following exception from within gi

My experience with GObject provided bindings is nonexistent prior to this, so I'm not sure if this is an issue with the binding definitions or my use of the API. Any help you can provide here would be appreciated.

Thank you.
