Description of Problem: Everytime I try to run a .exe file that uses Winforms
I've compiled, I get an Unhandled Exception. I'm using the WinForms hello world
from here http://mono-project.com/Mono_Basics#Winforms_Hello_World.

Steps to reproduce the problem:
1. Create a file called 'hello.cs' just like the one in Winforms Hello World
link above 

2. in the terminal:


   I also tried using Geoff Norton's Carbon implemention, so I did this instead


3. Compile the source file using

   gmcs hello.cs -pkg:dotnet

   or, using

   gmcs hello.cs -r:System.Windows.Forms.dll

4. Execute the program

   mono hello.exe

Actual Results:
jedd-haberstros-computer:~/desktop jeddhaberstro$ mono hello.exe

Unhandled Exception: System.ExecutionEngineException: SIGILL
  at <0x00000> <unknown method>
  at (wrapper managed-to-native) System.Diagnostics.StackTrace:get_trace
  at System.Diagnostics.StackTrace..ctor (System.Exception e, Int32 skipFrames,
Boolean needFileInfo, Boolean returnNativeFrames) [0x00000] 
  at System.Exception.get_StackTrace () [0x00000] 
  at System.Exception.ToString () [0x00000] 
  at System.Exception.ToString () [0x00000] 
  at System.Exception.ToString () [0x00000] 
  at System.Exception.ToString () [0x00000] 
  at <0x00000> <unknown method>
  at HelloWorld..ctor () [0x00000] 
  at (wrapper remoting-invoke-with-check) HelloWorld:.ctor ()
  at HelloWorld.Main () [0x00000] 

Expected Results:
A form windows using either the Quartz or Carbon backend.

How often does this happen? 
Everytime I execute a winforms application I have compiled (haven't tested
other winform application, except Reflector - see Addition information)

Additional Information:
When trying to execute the newest Reflector.exe I get this output:

jedd-haberstros-computer:~/desktop/reflector jeddhaberstro$ mono reflector.exe

** (reflector.exe:1210): WARNING **: exception inside UnhandledException
handler: Object reference not set to an instance of an object
