Support of private rooms on F-Chat (libpurple) is broken

[TomTheDragon]

I used to be able to join public and private rooms on F-Chat and i still can. But for some reason private rooms are shown as users now and not as a normal room, like public rooms.
When i try to join a private room by its ID, i can just see all of the messages from others writing in there, but there is just no user list.
