Test case

I get the following exception when clicking on the down arrow of a DomainUpDown
control when running mono-2-2 branch at r119053.

System.ArgumentOutOfRangeException: Index is less than 0 or more than or equal
to the list count.
Parameter name: index
0
  at System.Collections.ArrayList.ThrowNewArgumentOutOfRangeException
(System.String name, System.Object actual, System.String message) [0x00000]

  at System.Windows.Forms.NativeWindow.WndProc (IntPtr hWnd, Msg msg, IntPtr
wParam, IntPtr lParam) [0x00000] 

When I run the attached testcase on Windows and click the down button, it shows
"First" as I expect.  This behavior is also the same on Mono 1.9.1.
