Debug info from gdb:


=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================


The source code:

using System;
using Qyoto;

public class MainWindow : QMainWindow
{
public QTextEdit editor;
public MainWindow() : base()
{
SetupEditor();
SetCentralWidget(editor);
Resize(400, 200);
}
 private void SetupEditor()
{
editor = new QTextEdit();
}
 protected override void OnCloseEvent(QCloseEvent ev)
{
Console.WriteLine("On close event");
ev.Accept();
}
 public static int Main(String[] args)
{
new QApplication(args);
MainWindow w = new MainWindow();
//w.SetCentralWidget(new QTextEdit());
w.Show();
QApplication.Exec();
//Console.WriteLine("exiting");
return 0;
}

}

when run, program does only output error messages and return to command
line.

Also, if i change the source a bit like this:
.....

public static int Main(String[] args)
{
new QApplication(args);
QMainWindow w = new QMainWindow();
w.SetCentralWidget(new QTextEdit());
w.Show();
QApplication.Exec();
Console.WriteLine("exiting");
return 0;
}

everything is ok.

When using smokegen, smokeqt and qyoto compiled from source from here
ftp://ftp.kde.org/pub/kde/stable/4.8.0/src/
all working ok.
