At first, the automatic upgrade failed with:
Fatal error: Call to undefined method Piwik::getLoginPluginName() in /html/piwik/core/View.php on line 129
(this appears to be dev.piwik.org/trac/ticket/1331)
Then I got:
Notice: Undefined index: timezone in /html/piwik/core/Site.php on line 66

And now it’s just (at /piwik/index.php?module=CoreUpdater):
Fatal error: Class ‘Zend_Registry’ not found in /html/piwik/core/Updates.php on line 35
(it worked fine on another setup / server, using svn sources directly)
