Sign-on dialog won't open a second time, give traceback

Ths software center part of this is solved by updateing to the new api and adding a versionized dependency.

However I can reproduce the issues that mpt has. When I run the attached test code a couple of times (two times seems to be enough most of the time) and click cancel in the dialog I get no dialog anymore but instead:

error: lala Problem opening the Ubuntu SSO user interface. Traceback (most recent call last):
