you may have noticed that i586 Factory builds were broken due to missing libXv packages. This is fixed now.
On the other hand, I do activate some more rpmlint checks for Factory now. These become also effective, when you build _for_ Factory in your own project. These are the usual checks from rpmlint, but configured to stop building packages in important cases to get a minimum level of quality. We use them already for all packages build inside of Factory.
Please report, if you run into trouble with that.
