[jabber.el] Long strings instead of names in Google Talk

[Mandar M. <man...@gm...>]

I've been using emacs-jabber very happily for 1:1 chats on Google Hangouts, but recently, jabber-roster has started displaying strings of the form

 * 22r...@pu... Online    
 * 0ek...@pu... Away      
     MessagingA53984b2d - Away (), priority 0
     messaging-lcsw_hangouts_43734ED5 - Away (), priority 0
 * 0ze...@pu... Away      

in addition to regular names.

I just upgraded to the latest MELPA package, but that did not fix the problem. Could any one please suggest what the cause might be?

Thanks,
Mandar.
