The GUI tools don't actually run yum or the plugin code, that's done
by the packagekitd daemon.

What version PackageKit and yum are you using? Could you upload your
yum plugin somewhere public also please.

It depends on how your plugin works. PackageKit does some things a
little bit different to yum.

No. PackageKit is doing different things with the data, and is
exporting it in a different way to using the bare yum api.

What's your use case for adding and removing repos like you're suggesting?
