[Mono-winforms-list] Problems trying to run winforms samples

[John BouAntoun]

Hi guys,

I was trying to try the samples in the winforms module and all of them
seem to be failing with the same problem.

I have a fresh install of all sources on a new machine.

I installed cairo, libpixman and libgdiplus and all other deps.

In particular after successfully installing Managed Windows Forms I get
the following error message when running the swf-radiobuttons.exe:

mono swf-radiobuttons.exe
#region #line XplatUI Constructor called

Unhandled Exception: System.NullReferenceException: Object reference not

MyFormProject.MainForm:.ctor ()

All the samples have a NullReferenceException in
System.Drawing.GDIPlus.XXXXX methods.

Have I done anything wrong in setting up the environment?

Help would be much appreciated.
