This problem occurs because in the KstRvector constructor the specified tag name is overriden in the following code:

  if (in_file) {
    // use datasource as tag context for this RVector
    // allow unique vector names to be displayed at top-level
    setTagName(KstObjectTag(tag().tag(), in_file->tag(), false));
  }

However, the corresponding tagname in the curve attributes is not changed in the same way so the curve is left with a vector that could not be found. 

The solution is one of the following:
* not to override the vector tagname when it is loaded
* to update the curve's vector tagname similarly when loaded
* when the datasource is changed change the tagname at that point so the overriding of the vector tagname when it is loaded has no effect
