My "akonadi_nepomuktag_resource" is offline since KDE-4.13

Hi, My system if Fedora 20, with the kde, kde-testing, and kde-unstable repositories enabled. In Kmail, I have virtual mail directories, under "Tags". Since the update to KDE-4.13 (with Baloo), that "Tags" directory is marked as "Offline", and I do not have any way of toggle it online. In the Akonadi Console, that set of virtual directories is governed by a resource named "akonadi_nepomuktag_resource", but I do not see which Akonadi agent is responsible for it. Probably it is gone since the upgrade. How can I handle that issue? That is probably a bug in the migration agent. -- Laurent Rineau http://fedoraproject.org/wiki/LaurentRineau
