After the modification of Custom Attributes of an object, the promotion of that object by means of Transport Case, DB Unload and DB Load fails. The load step (ucybdbld) fails with the following error:

U00021161 ERROR: Transport case is inconsistent (processed object '' table 'OCA' ), loading to Database is not possible. Please contact Automic Support ! 

Setting traces on ucybdbld yields the following error:
