Unable to load plugin 'ExampleFeedburner'

After I tried to update to the latest Piwik version 1.12 (via auto update) my installation is broken and I get the following error:

Unable to load plugin 'ExampleFeedburner' because '/path/piwik/plugins/ExampleFeedburner/ExampleFeedburner.php' couldn't be found.

An indeed, the file mentioned above is missing on the server. But it is not in the package of the new version neither. What am I supposed to do?

Remove the ExampleFeedburner lines from the config.ini.php
