I have successfully tested it on a 9.0 and 10g server, but I have been able to reproduce it on a 9.2.0.4 server. I actually get an ORA-22922 error (nonexistent LOB value). This happens when the LOB Locator is freed. The only workaround I can think of at the moment is to ignore the error in TLOBLocator.Free.
