+Description of Problem:
+
+The following program exhibts different results with .Net than with Mono.
+The program also generates a Signal Segmentation vialation SIGSEGV. It does
+not chash on .Net.
+
+using System;
+using System.Windows.Forms;
+namespace TestFD
+{
+	class Class1
+	{
+		[STAThread]
+		static void Main(string[] args)
+		{
+			string[] f;
+			OpenFileDialog fd = new OpenFileDialog();
+			fd.Multiselect=true;
+			fd.ShowDialog();
+			Console.WriteLine("file name before = " + fd.FileNames[0]);
+			f=fd.FileNames;
+			f[0]="abc";
+			Console.WriteLine("file name after = " + fd.FileNames[0]);
+			fd.Dispose();
+		}
+	}
+}
+
+Steps to reproduce the problem:
+1. Compile and execute the above program. 
+2. In the OpenFileDialog window select a file and click Open
+3. 
+
+Actual Results:
+
+Mono System.Windows.Forms Assembly [Revision: 54007; built: 2005/12/6 14:35:24]
+Keyboard: United States keyboard layout (phantom key version)
+Gtk colorscheme read
+file name before = /home/kendaniels/Projects/TestFD/test.cs
+file name after = abc

+=================================================================
+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.

+Expected Results:
+ The Console output should be:
+
+file name before = /home/kendaniels/Projects/TestFD/test.cs
+file name after = /home/kendaniels/Projects/TestFD/test.cs
+
+The program should not crash.
+
+How often does this happen? 
+Every time
+
+Additional Information:
+Mono is from SVN on 2/3/06
+
+The program still crashes if everything is removed from Main(), except the
+new OpenFileDialog() and the ShowDialog().
