Phalcon\Loader removes leading charakter from subnamespace in getCheckedPath

Hallo, i got an

"PHP Fatal error:  Uncaught Error: Class 'fhac\idm\sva2idm\Config\Config' not found in /opt/sva2idm/app/cli.php:79" 

while using Phalcon\Loader. The reason is that the searchpath used by the Loader removes the leading character from the path.

Loader

$loader = new Loader();
$loader->registerNamespaces(require __DIR__ . '/../vendor/composer/autoload_psr4.php');

$eventsManager = new EventsManager();
$eventsManager->attach("loader:afterCheckClass", function (Event $event, Loader $loader)
{
echo print_r($loader->getNamespaces());
echo $loader->getCheckedPath();
echo "\n";
}
);
$loader->setEventsManager($eventsManager);

$loader->register();

Calling:

use fhac\idm\sva2idm\Config\Config;
$config = new Config();

Output:

Array
(
[fhac\idm\sva2idm\] => Array
(
[0] => /opt/sva2idm/app
)
.
.
.
)
CheckedPath: /opt/sva2idm/app/onfig/Config.php

Now the leading C of Config is missing: /opt/sva2idm/app/onfig/Config.php.
