Auth issues with twittering from jabber

For the last two week twitter@twitter.com has been "offline" in AdiumX. It looks grey - but you can send IM messages to it and that will update your twitts (I'm lhirlimann on twitter; gosh I need to update my foaf file), but you don't get any twitts from people you are following, and you need to log into the twitter website to see them. For a normal user , it looks like the jabber twittering gateway is offline and does not work anymore.This issues just made twitter unusable for me.
Looking around I found this interesting thread : http://getsatisfaction.com/twitter/topics/not_receiving_notifications_in_jabber_or_gtalk, with mostly peopel trying to delete the IM interface on twitter and readding it. I tried that a few times - but twitter stayed offline. While trying to get more information I found out that the account was waiting for an auth request - that seemed to never get through.
This morning I booted a machine where PSI was setup and found out that twitter@twitter.com did not appear in PSI's buddy list. So I started the whole add an IM device to your twitter account - and much to my surprised it worked ! So there is an issue somewhere in libpurple - because I also treid to do the same thing from within ichat (which to my knowledge uses libpurple). Issues is I have no idea on how I should properly report the issue to libpurple developers.
