RPM broken in FC4

[kevin.kempter at dataintellect.com]

All;

I'm going back to FC3 for now. FC4 is just too instable for my current needs. 
However I thought it may be helpful to post my latest issue with the RPM 
database (see below). Yum and RPM were working fine. Not sure what broke it 
last thing I remember doing is a yum install xine

Hope this helps someone... I'll probably move to FC4 later this year. keep up 
the good work.
