Fehlermeldung "external SIGSEGV"

[nahpets]

Habe mal den Quelltext ein bisserl verändert:

Delphi-Quellcode:

unit Unit1;

{$mode objfpc}{$H+}

interface

uses
  Classes, SysUtils, FileUtil, Forms, Controls, Graphics, Dialogs, ExtCtrls,
  Buttons;

type

  { TForm1 }

  TForm1 = class(TForm)
    BitBtn1: TBitBtn;
    BitBtn2: TBitBtn;
    Image1: TImage;
    PaintBox1: TPaintBox;
    procedure BitBtn1Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
  private
    { private declarations }
    procedure MyPaint(xWert, yWert:integer);
  public
    { public declarations }
  end;

  end;

var
  Form1: TForm1;

implementation

{$R *.lfm}

{ TForm1 }

procedure TForm1.FormCreate(Sender: TObject);
begin
  //Logo
  Image1.Picture.LoadFromFile('Logo.jpg');
end;

procedure TForm1.MyPaint(xWert, yWert: integer);
begin
  Paintbox1.Canvas.Pen.Width := 10;
  Paintbox1.Canvas.Pen.Color := clLime;
  Paintbox1.Canvas.MoveTo(xWert,yWert);
  Paintbox1.Canvas.LineTo(xWert,yWert);
end;

procedure TForm1.BitBtn1Click(Sender: TObject);
begin
  MyPaint(10, 10);
end;

end.

Schau mal bitte, ob es so funktioniert und wenn ja, erkläre uns bitte warum.
