I don't see what spec file aspect is causing this failure:

RPM build errors:

fedpkg-simple doesn't have this problem (presumably because it downloads
whatever is in the sources file, whether used or not), so the package
builds fine in Koji.

Any ideas?
Difference in opinions on specfile syntax :)
This is the regex rpkg uses to find the source/patch tags:
      r'^((source[0-9]*|patch[0-9]*)\s*:\s*(?P<val>.*))\s*$'[1]

Actually,

     r'^((source[0-9]*|patch[0-9]*):\s*(?P<val>.*))\s*$',

The line in my message was something I modified to test the hypothesis.

As you can see, it does not expect spaces between Source[0-9]* and
':'.
rpm, however, allows the spaces and there's 6 packages in Fedora
that use this syntax quirk.

Thanks, this certainly explains it.

Should I submitt a pull request for pyrpkg to use your first variant of
the regexp?  Or how should we deal with this?

FWIW, this could just as well be considered an rpm bug. There's no particular reason to support whitespace in that place, more likely it's just something that accidentally works.

If somebody cares enough, feel free to file upstream.
