[Launchpad Bug Tracker <620458@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

For some weeks the Apport retracers have started crashing as soon as
they try to access an attachment of a private bug. This has started to
happen independently of the data center firewall configuration (since I
can reproduce it locally as well) or python-launchpadlib and dependency
version bumps (since I get the same on the local checkout on ronne,
which hasn't been updated in ages). It seems that this regressed in
Launchpad itself, but I'm also filing it against python-launchpadlib for
a potential improvement of the error message, since it is very unclear.

Simple reproducer:

$ lp-shell 
>>> b=lp.bugs[614676]
>>> b.attachments[0].data
<lazr.restfulclient.resource.HostedFile object at 0x1d33a90>
>>> f = b.attachments[0].data.open()
Traceback (most recent call last):

This only happens on private bugs, public bugs work fine.
