 I've been noticing issues in Pidgin while using the MSN protocol. For some
 reason, some times it can take quite a few times in order to sucesfuly
 connecto to a server, with notification server errors like:

 {{{
 (17:21:45) dns: DNS query for 'nexus.passport.com' queued
 (17:21:45) dns: Created new DNS child 32423, there are now 1 children.
 (17:21:45) dns: Successfully sent DNS request to child 32423
 (17:22:18) dns: Got response for 'nexus.passport.com'
 (17:22:18) dnsquery: IP resolved for nexus.passport.com
 (17:22:18) proxy: Attempting connection to 65.54.179.216
 (17:22:18) proxy: Connecting to nexus.passport.com:443 with no proxy
 (17:22:18) proxy: Connection in progress
 (17:22:34) msn: servconn read error, len: 0 error: Success
 (17:22:34) msn: Connection error from Notification server
 (207.46.110.117): Reading error
 (17:22:34) msn: C: NS 000: OUT
 (17:22:34) account: Disconnecting account 0x81728e0
 (17:22:34) connection: Disconnecting connection 0x846cfc8
 }}}

 These errors appeared every now and then, but lately they've become quite
 worse, to the point i haven't been able to get Pidgin to login to MSN
 (using three different MSN accounts) for the past two days. The official
 MSN client seems to work fine.

 Another problem is that, even when i '''DO''' get connected, i keep
 getting this random issues with the switchboard error:

 {{{
 (16:18:45) msn: servconn read error, len: -1 error: Remote host closed
 connection.
 (16:18:45) msn: Connection error from Switchboard server (207.46.26.85):
 Reading error
 (16:18:45) msn: destroy httpconn (01B65A58)
 (16:18:51) msn: new httpconn (026ECCB8)
 (16:18:51) msn: C: NS 000: XFR 15 SB
 }}}

 These either manifest as a "failed to send due to switchboard error"
 warning on the conversation window (which ends up working after a few
 tries), or a subsequent disconnection, and it can happen every 5 minutes
 or every 5 hours - completely random. Sometimes it works fine for days and
 sometimes i get disconnected every time i try to open a new conversation.

 Using the HTTP method to connect didn't help to solve these issues, or to
 change how often they appear. Other protocols seem to work quite fine, and
 the client doesn't crash or misbehaves when these appear.

 Both of this issues are present on every Pidgin version from on the 2.2.x
 to 2.1.2 (it might very well happen before, but i haven't been keeping
 track).  or whatever is worth, it might be linked to the MSNP version
 used, since the server insists on sending update urls for the official
 client whenever i get through - is this something we might expect to get
 fixed with the merge of MSNP14?

 Attached to this ticket is a log of a series of connections attemps, all
 failed. Will gladly help with anything i can. Thanks in advance.
