NSWindow base() constructor crashing with NSInternalInconsistencyException on Monodevelop

Question

I am trying to run on Monodevelop (latest Git) a solution that runs fine on Xamarin.Mac

It crashes at the base() line:

public class SetupWindow : NSWindow {

    public List <NSButton> Buttons = new List <NSButton> ();
    public string Header;
    public string Description;
    private NSImage side_splash;
    private NSImageView side_splash_view;
    private NSTextField header_text_field;
    private NSTextField description_text_field;

    public SetupWindow () : base ()
    {
        SetFrame (new RectangleF (0, 0, 640, 420), true);

With this output:

Any idea what is going wrong?

Because of another problem, I commented out the lines that set images for NSApplication.SharedApplication.ApplicationIconImage and NSWorkspace.SharedWorkspace.SetIconforFile, could that be the problem?

A colleague tried on his brand new Mac, and gets the exact same problem.

Answer 1

The problem was fixed by adding these two lines before instantiating SetupWindow:

NSApplication.SharedApplication.ApplicationIconImage = image;
SetFolderIcon ();

Now the application runs fine.
