ORA-39244:Event to disable dropping null bit image header during relational select
For me this line seems most telling:

PL/SQL: could not find program unit being called: "SYS.DBMS_AQADM_SYS"


You should check to see if the user that you exported had a job scheduled using a program owned by someone else. If so you are trying to schedule a job for a program that does not exist. You can create the program, then do the import as long as the user who will own the program exists before you create the program as that user.
