+Summary: A problem related to System.Drawing.Text.PrivateFontCollection and its FontFamily members
+
+After creating new System.Drawing.Text.PrivateFontCollection and adding
+some FreeType font file paths using AddFontFile() method, a program crashes
+when trying to get Name property of any FontFamily object from Families
+property. The problem exists on Mono 1.1.13.2 with libgdiplus 1.1.13.2.
+
+Steps to reproduce the problem:
+Compile and run the following code:
+<<begin>>
+using System;
+using System.Drawing;
+using System.Drawing.Text;
+
+class MainClass {
+	public static void Main(string[] args)	{
+		PrivateFontCollection col = new System.Drawing.Text.PrivateFontCollection();
+		col.AddFontFile("/usr/X11R6/share/fonts/corefonts/arial.ttf");
+		foreach(System.Drawing.FontFamily f in col.Families) 	{
+			Console.WriteLine(f.Name);
+		}
+	}
+}
+<<end>>
+
+Actual Results:
+=================================================================
+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.
