** NB: Minimal screening in effect due to workload.

Testcase
~~~~~~~~~~~~~~~~~

Files:  BDETC.tar.Z

Steps:
sqlplus /nolog @setup
Creates a user TC with table to export

sqlplus /nolog @tc
Loads several rows to the table, exports it using expdp
then attempts to import it which fails.

Reproduced
~~~~~~~~~~
Reproduced in 10.1.0.3
Reproduced in RDBMS_MAIN_LINUX_050301

Diagnostic notes
~~~~~~~~~~~~~~~~
LONGS are a problem for NETWORK_LINK but I cannot see an restriction
that expdp/impdp should not be able to exp/imp LONG column data
when no network link is involved.
