I tested again the facebook account in Empathy and, in fact, the same
problem appeared. There are some little differences:
1) The problem appeared in one contact, not all contact at the same time
2) The problem delayed five minutes in this attempt (less than one
minute in jitsi contact list). The first attempt showed no problem in a
60 minutes testing session.
--->Correction: In a 60 minutes third test , I observed that 1) and 2)
don't ocurred anymore, and 1) was corrected after a couple of minutes in
the Empathy contact list in the second test. In any case, the frecuency
of the problem is notoriously much less in Empathy than Jitsi. I think
It must be a detail configuration in jitsi and other im clients that is
generating the problem.
I realize it's more convenient for Jitsi to take the blame because it's easier to get responses from us than it is from Facebook maintenance. Unfortunately however, there's nothing we could do about this.
I just tried Swift and Apple Messages and Adium. Swift and Apple Messages exhibited exactly the same behaviour as Jitsi: Contacts appear with or without names, then names disappear and reapper at random intervals. (Adium never showed anyone online but that might be a different issue).
The cause for this is clear and there really is no mystery: Facebook tells us the names and we update them. Facebook tells us you have no name and we show your JID. That's it.
There might be something that's causing FB's servers to act a bit differently in the case of Empathy (although this would probably take a few hours of statistics to determine) but I don't think we are going to be digging into what this is.
We have enough on our plates to now go and spend time on working around FB's bugs and idiosyncrasies.
A detail I saw: facebook requieres ssl/tls, and I didn't found an option
for a facebook standard configuration in "connection" tab, only a
regular authentication option; and also noted that facebook support
published a xml string related to vcards with the objective to "show
more friendly names".
If authentication was the problem you wouldn't be seeing any contacts at all (not just their names).

Can you post the link of the Facebook XMPP developers group, to
investigate what's wrong?
Facebook XMPP Developer Relations:
The group is closed though and I am not sure what there acceptance policies.
