Long poll exceptions on Eligius port 80

I only get this when connected to Eligius over port 80, when I connect on 8337 it never seems to occur. This is with the PhatK version of poclbm found. This wouldnt be a big deal except Ive got a few miners behind a firewall that will only allow port 80. Im using the phatk version of poclbm found here
