In gajim, what we do is to first ask with 223 to get bookmarks, if there 
is an error answer we request with 49, and save it with 223 (if server 
has pubsub)

We faced a problem with some server not replying to <iq>, or reply 
several hours later (yes yes): we don't get an error answer, so we never 
request with 49. So we setup a timeout, and if we don't get an answer to 
223 request within this timeout, we request with 49.
