Cannot add online accounts

[Victor gonzalez]

Environment:
unity8-deb on zesty

Steps:

1º Open system settings>accounts
2º Try to add any online account from the list

Expected result: window to login for google/U1/facebook/flickr is displayed
Current result: when I click on any account on the list it just starts to load but no window or message is displayed

Confirming. Here's the logs -- it seems it has loaded the XCB platform plugin, for some reason:

The dbus daemon running in the unity8 session does not export the QT_QPA_PLATFORM environment variable. This was fixed for bug 1300921, but it appears that later on the changes got lost.

Attaching the environment as dumped by the online-accounts-service dbus service.

As a side note, note also how the XDG_CURRENT_DESKTOP is incorrectly set: I was running unity7, but then I logged out and relogged into unity8, but according to this variable we are still in unity7.
