Rhino Crash on invalid toString

Dear David,

I just encountered a nice phenomena: I made a mistake in my toString method in a custom VB Param (Particle inherits GH_Param):

Public Overrides Function ToString() As String
Return "Particle at {" + Position.X + ";" + Position.Y + ";" + Position.Z + "}"
End Function

Which of course should be:

Public Overrides Function ToString() As String
Return "Particle at {" + Position.X.ToString + ";" + Position.Y.ToString + ";" + Position.Z.ToString + "}"
End Function

When connecting a panel to the output there will be a nice error. However: when hovering the solution Rhino will crash. Not sure if this is a bug, but if there is a way to catch the error it would of course make the world a better place.

Enjoy Delft!
