bzr supports two http libraries, the external pycurl, and the internal 
urllib. pycurl is currently preferred if available, but that may change
soon.

The issue here is a problem when talking to alioth using urllib, which
works fine when using pycurl, so it's not simply a case of a dependency
not being installed as you state. These bugs are about the same issue
