It seems something wrong happens during "fedpkg retire" for this package.

It appears as "orphan" in pkgdb, but not as blocked in koji.

{{{
$ koji list-pkgs --tag=f22 --owner=remi --show-blocked | grep channel
php-channel-nrk f18 remi
php-channel-bartlett f18 remi
php-channel-phpunit f21 remi [BLOCKED]
php-channel-theseer f18 remi

}}}

So please block php-channel-bartlett in fedora 21 and rawhide.
