There is a way, but it has become harder with every release.

– Intrepid: enter something in the “away cause” field, pidgin will
connect
– Jaunty: stop NetworkManager while pidgin is running
– Karmic: /sbin/stop network-manager before pidgin is started

“sudo /sbin/stop network-manager” worked like a charm on Lucid! 


And restart pidgin or if pidgin still doesn’t connect use command “pidgin -f”
