As noted by Remi Collet at [1]:
""horde" is the old application (version 3) build from a single tarball
(but still available in the repository)
horde is now distributed via a pear channel and split in ~100 packages.
php-pear-Horde-Util 2.3.0 (with this fix) is already in the repository
(but not yet used as pear-horde-horde 5.1.5 is still under review)."
Sorry for the noise!
