branch command crashes with "gaierror: (1, 'address family not supported')"

[davidedb]

bzr crashes when running the following command:

bzr branch lp:bzr-fastimport fastimport

with error message:

bzr: ERROR: socket.gaierror: (1, 'address family not supported')

More details in the attached file .bzr.log
I suspect this depend on the fact that I'm below a proxy/firewall which block the HTTPS traffic.
Yet I have the same error when I set the environment variable HTTP_PROXY or HTTPS_PROXY.

It would be better in any case to catch such an error and print a more meaningful error message.

I believe this is just a duplicate of bug #186920 which is because the python standard libraries "xmlrpc" code doesn't handle proxies.

Does it work if you do:

bzr branch http://bazaar.launchpad.net/~bzr/bzr-fastimport/fastimport.dev

(Which is where lp:bzr-fastimport points).

Yes, it's probably a duplicate of that bug (I was not aware of it): in my environment, too, name resolution is performed by the proxy server (i.e. commands such as 'ping www.launchpad.net' fail, yet I can reach the server/web page with my browser).
Is there any solution/work-around?

If I use the URL you suggest, everything works smoothly.
Is there a general rule for converting URLs from lp: protocol to http: protocol?

If you type in 'http://code.launchpad.net/+branch/<foo>', you'll be redirected to a page that matches 'lp:<foo>'. If you then change the domain from 'code' to 'bazaar' and the protocol from 'https' to 'http' or 'bzr+ssh', you have the URL of the branch.
