[Philip Withnall <pwithnall src gnome org>]

commit 96bf4cf74db1b5c4be55202dcd0e7701ea6cbcd3

    Only unref the EmpathyIndividualView after emptying the group hash table
    
    Otherwise, unreffing the view could cause it to be destroyed, and thus
    emptying the hash table will write into freed memory and crash.
