The CURLOPT_CAINFO option in libcurl looks like something bzr could set to
specify a certificate to use. (see
For the Launchpad case, it's probably better to make sure that the pycurl we
distribute in the installer already has the necessary CA cert in its default
bundle. I'm not sure what's involved in doing that, but it would seem to be the
best solution for this to work out-of-the-box for our Windows users. Perhaps we
should talk to pycurl upstream?
