dict.jabbim.cz is not discovered properly
When trying to go through Service Discovery with gajim 0.12beta1 on jabber.cz I can see there is a service dict.jabbim.cz, but I cannot do anything with it, because all buttons are greyed out (see attached screenshot). However, it works correctly and shows a long list of dictionaries, which can be added to the roster in psi (0.12, both on Fedora/Rawhide).
The same can be seen in the logs of the XMPP chatter.
See attached attachments.
