Comment 5 for bug 1570986

Yes Sam, that's correct: accounts providers are visible only if there is at least one installed application which can use such accounts. Since at the moment there isn't such an app, the account won't be visible.

If you install this test application, then the owncloud account will appear: http://www.mardy.it/archivos/owncloud-bookmarks.mardy_0.1_armhf.click
