Title:
AccessToken.from_string() crashes on python3
Status in launchpadlib :
Fix Released
Status in python-launchpadlib package in Ubuntu:
Fix Released
Status in python-launchpadlib source package in Xenial:
Fix Released
Bug description:
[Impact]
* Unable to renew/relogin with a new oauth token, using python3 scripts
* python2 APIs work (because python2 does not care about str vs bytes)
[Test Case]
* Attempt login_with() using python3 and an expired/invalid existing token
* Relogin should be successful, without crashing scripts
[Regression Potential]
* No change in behaviour on python2 (which is what used by reverse
dependencies)
* this is a backport to fix python3 behaviour, for all the newly ported
maintainance scripts in python3 that prefer to run on "stable" systems
[Other Info]
* Well tested in later releases, and with users running from trunk.
* I believe this still is not published in the cheeseshop.
[Original bug report]
Trying to use Launchpad.login_with() on python3, after fixing the
earlier bug yields this issue:
Traceback (most recent call last):

key = params['oauth_token']
KeyError: 'oauth_token'
The problem is that params has b'oauth_token', not 'oauth_token',
which matters on python3
