I ran fedora-review on [https://bugzilla.redhat.com/show_bug.cgi?id=1241919 this request for python-line_profiler], and it reported an issue that a package with that name already exists (from CheckNoNameConflict in generic.py).

It turns out that the package in question existed at one point and had been retired, however, since fedora-review generated old-style URLs it caused some initial confusion (especially since pkgdb doesn't let you search for retired packages for some reason)

generated URL: https://admin.fedoraproject.org/pkgdb/acls/name/python-line_profiler

actual URL: https://admin.fedoraproject.org/pkgdb/package/python-line_profiler

We should probably distinguish between an existing active package and a retired package -- especially if the package has been retired for a long time, but that probably needs further discussion first.
