Can anyone tell me, is this me doing something wrong or is it a current bug in 
the code?

(Assuming I am doing the build properly) mono is the current version updated 
10 minutes ago.

Test program simply declares an OpenFileDialog

Program throws:

Unhandled Exception: System.ArgumentNullException: Cannot add null image
Parameter name: value
in <0x00104> System.Windows.Forms.ImageList+ImageCollection:Add 
(System.Drawing.Image value)
in <0x001a6> System.Windows.Forms.MWFFileView:.ctor ()
in (wrapper remoting-invoke-with-check) System.Windows.Forms.MWFFileView:.ctor
