Bug Description

python-httplib2 added support for checking https certificates in 0.7.0. The packages currently in Natty and older don't perform any certificate validation, permitting man in the middle attacks on any software that uses the library and doesn't perform checks of it's own.

For Oneiric, see bug 882027: it doesn't use the system CA certs by default.
