The solution here is simple : ALWAYS use a version-release for
"Obsoletes:" lines. Period. This would have prevented this problem
from ever existing. Same goes for "Provides:", that way you keep much
more control.

Of course, you won't be able to go fix the old package now... pretty
much like an existing epoch.

I'd like to see the default Fedora rpmlint configuration error on
"Obsoletes:" without a version, and warn on "Provides:" without one
either, if that's not already the case.
