[Gtk-sharp-list] Mono / GTK# program crashing

[Simian Man]

Hello all,

I'm sure this is a simple problem, but as I'm new to C#, GTK, and
Monodevelop, I can't seem to figure it out.

I started by creating a new GTK# program which gives you a simple skeleton
that opens a blank window and nothing else.  When I try to add anything at
all with the GUI designer, however, the program crashes with:

Unhandled Exception: System.NullReferenceException: Object reference not set
to an instance of an object
  at MainWindow.Build () [0x002dd] in
/home/ian/projects/congo-paint/gtk-gui/MainWindow.cs:83 
  at MainWindow..ctor () [0x00007] in
/home/ian/projects/congo-paint/MainWindow.cs:8 
  at congopaint.MainClass.Main (System.String[] args) [0x00005] in
/home/ian/projects/congo-paint/Main.cs:17


The line of code in question is:


this.menubar1 = ((Gtk.MenuBar)(this.UIManager.GetWidget("/menubar1")));

this.menubar1.Name = "menubar1";



I'm assuming that this.menubar1 is NULL at this point, but this code was
automatically generated by the GUI designer, so I don't know what to do
about it.

Does anybody have any ideas?
