Not sure if you're still having this problem, but the only version I've got to work on my MacBook Pro is Jabber 4.8.8. No other version has recognized the computer's webcam. I'm not planning to update until I can confirm newer versions work.
I have seen this problem under two different scenarios. First time was when I tried to load jabber on my mac. All I got was a greenish screen. After doing some research, I discovered that the same kind of problem occurred with Skype users and it was associated with photobooth. So, I stopped photobooth and the problem went away.
The other situation was when some of our users upgraded to Maverick. So, the older version of Jabber would not work (camera would not work). So, we got a newer version of jabber for mac and the problem went away.
