Error does not appear if you are try to add multiple structure elements with a count of one or more!

Affected version: Kitodo.Production 2.1.0

Thank you for the stack trace. The problem seems clear: Without images, SelectItem alleSeiten[] is not initialized (null) and the for-loop in Metadaten.java l. 2032 breaks.
