no longer can select eperson after upgrade to 5.6

After upgrading our DSpace 5.4 server to DSpace 5.6 we no longer can select epersons. Activating the button at /tools/eperson-list?multiple=true throws a database error.

Exception:

java.sql.SQLSyntaxErrorException: ORA-00932: inconsistent datatypes: expected - got CLOB
