The default association for rpms seems to be archive manager and not pk-install-package.
How are you opening them? From a web-browser or double clicking on them?
double clicking in nautilus
Can you please update to shared-mime-info version 0.23-6 and retest please. Thanks.
I'll stick it in the appropriate state so that the triagers see it and can try too (as there's a good chance one of them will get to it before I do)
Works. Jeremy could you tag this one f9-final if it's not in the queue already? http://koji.fedoraproject.org/koji/buildinfo?buildID=46273
Cheers for testing so quick.
