I'd like to bring attention of anaconda developers to bug #374891 https://bugzilla.redhat.com/show_bug.cgi?id=374891
This is a long term bug in anaconda causing crash at update. Tim Liim does there a very good analysis and proposes solution to fix this. It's pity that F9 is still affected, but I am looking forward to F10 to fix this.
