They haven't been retired or blocked and get rebuilt during mass-rebuilds.

Visit above Wiki pages and retire the obsolete packages properly
for Rawhide _and_ Fedora 20 (since that is still possible, too).

Complete all steps as explained in the Wiki.
It is important to block/withdraw the obsolete builds also from F20.
For older dists, packages cannot be pulled anymore.

Afterwards, fix the Obsoletes tag in "ibus-typing-booster".
Prefer "less than" over "less than or equal" in the Obsoletes tags.
Don't use the dist tag in the specified version-release values.
Specify the _next_ Release value that is higher than the Release prefix
of the last published build. If not doing that, even a minor update for
the old dists would break the Obsoletes tag.
Add only a single pair of Provides/Obsoletes per package.

The following would be safe, provided that the packages get blocked from F20:

  Obsoletes: ibus-european-table < 1.1.6-5
  Obsoletes: ibus-hunspell-table < 0.0.8-5

I offer to send you a full cleanup patch for current git, after you manage
to retire and block the obsolete packages.
