"koji regen-repo dist-test-build" command fails

[Eric Zhong]

"koji regen-repo dist-test-build"  command fails,

kojid, kojira, httpd, postgresql are all running.
selinux is disabled

I debug the kojid and create_local_repo() not be exe, because pkglist is
empty.
i can't find who create this file, and when it be created.

Have somebody got this problem ?
I find out some old articles from mail list, but all are not help!

=======================================================
        if os.path.getsize(pkglist) > 0:
            # don't call createrepo with an empty pkglist or it'll
            # add every Koji-managed rpm to the repodata
            self.create_local_repo(rinfo, arch, pkglist, groupdata, oldrepo)
========================================================
