Facebook XMPP screwed with the contacts, and now roster is broken
Where Facebook previously used u12434524 for usernames, now it's switched to -123342314, which APPARENTLY confuses Smack. Sigh.
This has been resolved via a number of patches.
One of the bizarre parts of this is that I'm not sure smack IS failing. =/ At least not the one I upgraded to. Well it's failing on something – but it appears that it might be that the roster handler is not doing it's job right. I believe I have a workaround for this but something else is going on so not closing this until I'm sure.
