Muc bugs?

I try to implement a client by using extensively the status codes jep 0045 defines for Multi User Conference.

I can see that in many cases these status codes won’'t ever come from Wildfire!

Is there something wrong with my client or is the implementation buggy (or version out of date?)

For example, when a presence comes to my client that belongs to me, why don’'t i get the status code 110, that tells me that?

Thanks in advance!
