[IronPython] TreeStore ...

[Zoltan Varga]

                                          Hi,

  This doesn't work because the TreeStore ctor is defined as:

		public TreeStore (params GLib.GType[] types)

while IronPython converts the arguments to an object[] array, not to the 
array type required by the method. The place where this needs to be fixed is
ReflectedMethodBase.BindArgs (), specially this line:

				if (IsParamArray(pi)) {
					//!!! add error checking and non-object arrays

so this is a bug/limitation in the current IronPython release.

                         Zoltan
