When a rpm specified in comps doesn't exist in RPMS (or
isn't found for the right architecture) anaconda fails with
a python stack trace.
Instead it should give an error (or a list of errors) and
let the user continue installing as many packages as
(besides, anaconda has no entry in bugtraq; see reopened
ticket -- and I'm forced to guess!!!)
assigne dto installer
This issue is fixed in the latest installer.
