+Summary: Graphics.FromImage NullReferneceException
+
+(mono installed using the linux installer, version 1.1.8.2.
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+
+The following program fails:
+
+using System;
+using System.Drawing;
+
+namespace t
+{
+    public class test {
+        static void Main(string[] arg)
+        {
+            Bitmap b1 = new Bitmap(10,10);
+            Graphics gfx1 = Graphics.FromImage(b1);
+            Console.WriteLine("OK");
+        }
+    }
+}
+
+
+Actual Results:
+Unhandled Exception: System.NullReferenceException: Object reference not
+set to an instance of an object
+in <0x00000> <unknown method>
+in (wrapper managed-to-native)
+System.Drawing.GDIPlus:GdipGetImageGraphicsContext (intptr,intptr&)
+in <0x00057> System.Drawing.Graphics:FromImage (System.Drawing.Image image)
+in <0x00036> t.test:Main (System.String[] arg)
+
+
+
+Expected Results:
+
+Pass through without exception, outputting OK.
+Copying the .EXE from Linux to a Windows XP box and running it under the MS
+.Net Framework works, as well as compiling the same source using Visual
+Studio and running it on windows. Taking the visualstudio-compiled file
+over to linux and the problem is back.
+
+
+How often does this happen? 
+
+Every time.
+
+
+Additional Information:
+
+Same problem occurs if I do new Bitmap("myfile.png") which is what I was
+actually trying to do when hitting this problem.
