104 Unhelpful read error message.

    Trying to load the faulty iv-file below will correctly terminate
    the import operation with an error message, but the error message
    is really lousy:

    --------8<------------- [snip] --------------8<------------- [snip]
    #Inventor V2.1 ascii

    SeparatorKit {
      childList {
        ShapeKit {
          shape Cone{}
        }
      }
    }
    --------8<------------- [snip] --------------8<------------- [snip]

    Results in:

        Coin read error: Expected '}'; got '{'
                Occurred at line   4 in hepp.iv

    ...which just seems wrong, or at least completely unhelpful.

    This is a low priority item.

    Just for reference, the corrected iv-file in this case would look
    something like this:

    --------8<------------- [snip] --------------8<------------- [snip]
    #Inventor V2.1 ascii

    SeparatorKit {
      childList NodeKitListPart {
        containerNode Group {
          ShapeKit {
            shape Cone { }
          }
        }
      }
    }
    --------8<------------- [snip] --------------8<------------- [snip]

    UPDATE 20060131 kintel: I think this problem is the same or closely
    related to bug ''20041105--incorrect_error_message_on_invalid_file.txt''.
