It seems to me that this is a pre-release snapshot, because there seems to be no upstream release of version 0.1 of this package. Then the RPM release tag has to follow this schema:
0.%{X}.%{alphatag}

Which is in this case:
0.1.svn%{svn_rev}%{?dist}


https://fedoraproject.org/wiki/Packaging/NamingGuidelines#Pre-Release_packages

Upstream is really bad about versioned releases for trac plugins.  But I see your point, I was following the post-release snapshot guidelines, assuming that the first version ever published was the 0.1 "release".

A "release" per se is unlikely to ever occur for this package, so it will be forever a pre-release I guess.

New spec: http://jstanley.fedorapeople.org/trac-watchlist-plugin.spec
New SRPM: http://jstanley.fedorapeople.org/trac-watchlist-plugin-0.1-0.2.svn5357.fc10.src.rpm

Oh, and the 0.1 version came from setup.py - I didn't just pull it from mid-air :)

Please change the two occurences of %define to %global before importing the
package into Fedora. Except for this minor issue the package looks good and is
therefore APPROVED.

You need to create a CVS admin request to proceed, and don't forget to change the %define to %global.

Oops, looks like I completely forgot about this - sorry about that!

It seems this happened again.

https://admin.fedoraproject.org/updates/FEDORA-EPEL-2011-5335/trac-watchlist-plugin-0.5-0.2.svn11062.el6

I don't know if Fedora branches/updates are needed/wanted.

It has been built for Fedora 17 and 18, therefore I do not see any value in keeping this bug open.
