For the guzzle/guzzle package (as an example that uncovered this), our autoloading fails.

First symptom is the error Cannot redeclare class Zend_Log in …/Libraries/guzzle/guzzle/tests/Guzzle/Tests/Log/Zend_Log.php on line 30 which cannot be resolved using object.excludeClasses configuration. Indeed the PackageStates.php contains:

    'guzzle.guzzle' => 
    array (
      'manifestPath' => '',
      'state' => 'active',
      'packagePath' => 'Libraries/guzzle/guzzle/',
      'classesPath' => 'tests/',
    ),

Note the classesPath entry… this is probably caused by this part of Guzzle's composer manifest:

    "autoload": {
        "psr-0": {
            "Guzzle\\Tests": "tests/",
            "Guzzle": "src/" 
        }
    },
