EDIT

The same problem as described in #6527#note-6 also appears in media bulk editor if you try to delete a media that is used for a protolog (TaxonNameDescription). The check only seems to check for TaxonDescription and SpecimenDescription. But there are multiple places where media can be added and reference. We ALWAYS need a general getReferencingObjects check in case any unexpected reference still exists. This is also important for model changes.

Currently if you delete the image and afterwards you open the name the protolog was attached to you get an ObjectNotFoundException exception which pops up in loop (this should also never happen, for NO exception, please feel free to open a new ticket for this).
