Installation redirect to undefined; all_tests.php failing

Installation redirects to "undefined". Not sure if it's a regression from the Zend_Session patch, but saw this each time I chose to delete existing tables:

Unit Tests all_tests.php fails in tests/core/API/DocumentationGenerator.test.php, but succeeds when test is run by itself. Where is it getting website id 2?

Exception: ../tests/core/API/DocumentationGenerator.test.php -> Test_Piwik_API_DocumentationGenerator -> test_callableApiMethods_doNotFail -> Unexpected exception of type [Piwik_Access_NoAccessException] with message [You can't access this resource as it requires a 'view' access for the website id = 2.] in [/home/apang/work/piwik/trunk/core/Access.php line 340]

Re: Unit Tests. The problem is interdependencies and interactions between unit tests. The DocumentationGenerator.test.php cannot be run after SitesManager.test.php. Database.test.php must run before other table-based tests.

(In [1287]) fixes #845 - php 5.3 backward incompatibilities and deprecated functionality; quick fixes #851 - unit tests; also fix redirect error in Installation when deleting existing tables
