Sometimes we get the following exception:

System.ArgumentException: An item with the same key has already been added.
   at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)
   at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
   at ICSharpCode.SharpDevelop.Dom.NRefactoryResolver.NRefactoryASTConvertVisitor.VisitAttributes(IList`1 attributes, ClassFinder context)

Unfortunatelly I cannot provide scenario to reproduce, this issue is quite rare.
