+Description of Problem:
+Graphics.FillPie hangs for this particular case.
+
+Steps to reproduce the problem:
+1. Try compiling and running the following code,
+using System;
+using System.Drawing;
+                                                                          
+                                                   
+public class Test {
+                                                                          
+                                                           public static
+void Main () {
+
+                Pen bluePen = new Pen (Color.Blue);
+                Bitmap bmp = new Bitmap (400, 400);
+                                                                          
+                                                                   Graphics
+dc = Graphics.FromImage (bmp);
+
+                Rectangle rect = new Rectangle (200, 600, 249, 250);
+                dc.FillPie (Brushes.Green, rect, 380, -20);
+                                                                          
+                                                   
+/* This commented code works fine.
+                Rectangle rect1 = new Rectangle (200, 600, 249, 251);
+                dc.FillPie (Brushes.Green, rect1, 380, -20);
+                                                                          
+                                                   
+                Rectangle rect2 = new Rectangle (200, 600, 249, 250);
+                dc.DrawPie (bluePen, rect2, 380, -20);
+                                                                          
+                                                   */
+
+                bmp.Save("fillpie.png", ImageFormat.Png);
+        }
+                                                                          
+                                                   }
+
+Actual Results:
+Program hangs.
+
+Expected Results:
+Program should run fine and draw a partially filled pie.
+
+How often does this happen? 
+Always.
+
+Additional Information:
+When the difference between width and height of rectangle is 1 and angles
+sum is close to 360, then cairo_fill operation seems to be hanging. It
+might be a cairo problem.
