I want to test an example of an application of a simple browser. Here is the source code:
using System;
using Gtk;
using Gecko;
class Browser{
public static void Main(string[] args)
{
Application.Init();
Browser b=new Browser();
Application.Run();
}
Gecko.WebControl webctl;
Gtk.Entry urlbox;
static string greeting =
"<html><head><title>My Browser</title></head>" +
"<body><h1>Hello!</h1><p>Type a URL in the box " +
"and press enter.</p></body></html>";
public Browser ( )
{
Window w = new Window ("Browser test");
VBox v = new VBox ( );
w.Add (v);
urlbox=new Entry();
urlbox.Activated += Load_Url;
webctl= new WebControl();
webctl.SetSizeRequest(450,350);
v.PackStart(urlbox,false,false,0);
v.PackEnd(webctl,true,true,0);
w.ShowAll();
w.DeleteEvent +=Window_Delete;
webctl.RenderData(greeting,"file://tmp","text/html");
}
void Load_Url(object o, EventArgs args)
{
webctl.LoadUrl(urlbox.Text);
}
void Window_Delete(object o, DeleteEventArgs args)
{
Application.Quit();
}
}
There is no error of compilation. But when I want to execute the application, there is the following error:
Stacktrace:

=================================================================
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.
=================================================================
I also executed the command: MONO_LOG_LEVEL=debug mono Browser.exe. Everything is OK until:
Mono-INFO: Searching for 'gtk_widget_show_all'.
Mono-INFO: Probing 'gtk_widget_show_all'.
Mono-INFO: Found as 'gtk_widget_show_all'.
Stacktrace:

Has anybody already had this kind of error? Please help me...
Thanks
PS: I use: Fedora 9, monodevelop 1.0.7, mono 1.9.1
