Comment 27 for bug 198646

I'm having this or a similar problem with bazaar 2.3.1 and 2.2.2. I'm getting this error:

-----8<-----
 * bzr branch start -->

You have not informed bzr of your Launchpad ID, and you must do this to

The breaking HTTP looks like this (wireshark output):

The above request is the only one in the stream with Content-Type: multipart/byteranges. Notice that there are not two Content-Type headers in the server response. I'm also behind a transparent proxy server.
