Comment 23 for bug 365874

Got the same error while trying to set up bzr access through corporate proxy server with authentication.

I set the "http_proxy" environment to include user and password, this gives the following error:

bzr: ERROR: pycurl.error: (65, "necessary data rewind wasn't possible\n")
