More info:
 * I am using KDE.
 * Reproducible 100% by first authenticating so the data gets stored in kwallet, and the 2nd invocation of the program results in the stack trace.
 * The data in kwallet looks fine and not corrupt:

[1]
consumer_secret =
access_token = zVM5MwvXXXXXXXXVtktkZ
consumer_key = System-wide: Ubuntu (beast)
access_secret = q0n81J6LnM58gGMsXXXXXXXXXXXXXXXXxCVq2SKFCBwRl3FKSt6c3HHqk1vqBqNHvKxVrK0Q0

(tokens deliberately part-corrupted with XXXes here)

This and bug 745801 might be related.

I found out what was wrong, it's a problem in launchpadlib. See bug 877374
