1. Load a DICOM file into MITK
2. chose DICOM reader v2 (autoselect)
3. see how the Study Instance UID (0020,000D) and the Series Instance UID (0020,000E) are displayed instead of a readable data node name.
This was different before, the change was introduced in D166, as far as I can see.
I'd like to discuss this change and think about possible alternatives (see also T19477).
