An insufficient or ancient Obsoletes tag has been discovered in the package. It should either be corrected or dropped. The tag is superfluous, because it doesn't obsolete a package found in Fedora 16 and newer, and that package is ancient: ufraw-0:0.18-3.fc16.i686 is oldest ufraw < 0:0.10 obsoleted by ufraw-0:0.19.2-4.fc20.i686 ufraw < 0:0.10 obsoleted by ufraw-cinepaint-0:0.19.2-2.fc19.i686 ufraw < 0:0.10 obsoleted by ufraw-common-0:0.19.2-4.fc20.i686 ufraw < 0:0.10 obsoleted by ufraw-gimp-0:0.19.2-4.fc20.i686 [semi-automated bug report]
I've fixed this in dist-git, the next build should pick this up.
