This is really an issue for Fedora release engineering, not fedmsg. However: If this is part of building the boot.iso stuff, thats been broken. ;) first by grub2 broken deps, then tigervnc broken deps (which Kevin Fenzi just fixed this morning)
I kept getting "invalid component". Do the Fedora release engineering folks use bugzilla or trac bug tool?
Ah, it's trac. They are over here: https://fedorahosted.org/rel-eng/report/1
closing as not a bug. this is part of the process and how things are designed. if rawhide is not installable then there will not be a .composeinfo file present. if there is any questions please ask in #fedora-releng or send an email to the releng list.
