umbrello/model_utils.cpp function findUMLObject()
- In the for-loop over `pkg' initial part, do not enter into tests of `name'
  against pkg->name() if `type' does not match pkg->baseType().

My current testing shows that this appears to fix the problem.
However, I will wait with setting the bug to RESOLVED until more testing is
done. If somebody can confirm that it works, that would be helpful.
