TYPO3.Flow

OK here is a strange one:
I'm currently writing a server-administration tool with FLOW3. As I want to connect to other systems as well, I make use of the libssh2 library (http://www.php.net/manual/en/book.ssh2.php).
So my first simple step was basically this:

$connection = ssh2_connect('localhost', 22);
ssh2_auth_none($connection, 'myuser');

I did this in the StandardController of my package, that i just kickstarted before, so there is nothing in between. The result of this is a RuntimeException somewhere out of the AOP stuff when rendering the View (I guess) [attached that result].
---
It's getting even stranger, when I put the result of the authentication method into a variable like this:

$connection = ssh2_connect('localhost', 22);
$supportedAuthenticationMethods = ssh2_auth_none($connection, 'myuser');

This results in a fatal error:

Fatal error: Call to a member function getVariableContainer() on a non-object in /var/www/localhost/htdocs/flow3/Packages/Global/Fluid/Classes/View/TemplateView.php on line 171

As this stuff of course doesnt belong the StandardController (DDD), I put it into its own class => Same result

BTW: I'm using PHP 5.3_RC2, FLOW3_alpha1 and head-revision of libssh2 on a Gentoo 64bit Linux system.
