Shotwell remote publishing does not work in Unity/Gnome/XFCE on utopic

[Gabor]

When selecting another publishing destination than Piwigo, the dialog closes itself.

* Impact
the publish dialog fails to open the online account configuration

* Test case
- click on a photo
- select 'Publish' in the 'File' menu
- click on the top right corner where it says 'Piwigo'
- click on 'Add more accounts...'

that should open the account configuration panel from settings

Xubuntu 14.10 final release 64bit
Shotwell 0.20.1-0ubuntu1
PicasaWeb publish plugin eanbled

When I run shotwell with this command
& SHOTWELL_LOG=1 SHOTWELL_LOG_FILE=:console: shotwell
then here is the result when I click on Publish button then select the create new account option in the top right corner.
