Do you think this bug is related to a plugin?

This looks like something is missing from your Python installation. What OS are you using?

[Martin Pool (mbp)]

This works for me on Jaunty:

python -c "import httplib;print httplib.HTTPSConnection"

I guess it fails for you?

You're probably missing the python SSL package. On Ubuntu this is part of python2.6 so we don't give a specific message for it, but it's probably possible to build Python without it.

We should probably detect the absence of this and give a clearer error. httplib swallows the ImportError so we'd have to detect HTTPSConnection is missing.

[Vincent Ladeuil (vila)]

In my experience this is due to an incomplete python (i.e. missing the _ssl module).
It's weird that you seem to experience that with an Ubuntu distro where py26 comes with the _ssl module.

Anyway, there is a genuine bug here as bzr shouldn't backtrace but just not try to support https if the required python module is not present.

[Martin Pool (mbp)]

His machine seems to be called Ubuntu but that's not quite a guarantee :)

[Gary Chou (gary-chou)]

I am running Ubuntu 9.04.

@bialix, done, except that unfortunately your comment has propagated the link :)

[Alexander Belchenko (bialix)]

I'm very sorry.

[Martin Pool (mbp)]

It's not a problem, I asked for yours to be removed or edited too.
