Ok, the sources are at the end of the message, but currently I have another 
problem. If I run anything with the Qt-bindings, I get this:

I don't know why this happens, I really didn't do ANYTHING on my system, I 
just started the program again and this was the result.


but now my sources:

using System;
using Qt;

class MainForm : QDialog
{
	public static void Main (string[] args)
	{
		Qt.QApplication qa = new Qt.QApplication(args);
		MainForm mf = new MainForm();
		mf.Show();
		qa.SetMainWidget(mf);
		qa.Exec();
	}
	
	public MainForm()
	{
		this.Show();
		QVBoxLayout qgrid = new QVBoxLayout(this);
		qgrid.SetAutoAdd(true);
		QTextEdit te = new QTextEdit(this);
		te.Show();
		QPushButton button = new QPushButton(this);
		button.SetCaption("Hello World!");
		button.Show();
	}
}


and the problem also occurs with some constructors with more than 1 argument.
