I've got a very similar bug when trying to add (we tried a few times with different directions) an user (who has a multi-device account) to my jami-client-android. Now it's perpetually in the state "Invitations received" in the contact list (and in the contact list proper) with different swarm IDs. The person gets stuff i send to the added contact on their jami-client-qt, but can't get anything on jami-client-android (and they have two me's in their contact list, and i can't get anything they send to either of them either); and when i go into the "inviting" contact, it just says "Downloading conversation from peer" for a few days now.

Gentoo. Ah right, it's broken there as well. After fixing it manually it tries to download dbus-c++, and dbus-c++ is also already installed, and has the correct version in .pc.
Maing it awkward to package jami-daemon in a distro.
