EHP5 migration, IMPORT command

Hello, I am participating as "ABAPer" in a migration to EHP5.

I have a problem with the import command, where it does not work for tables that contain fields of type LRAW, ie, the command is not executed, returns the following DUMP :

Category ABAP Programming Error
Error tpo.exec. IMPORT_ALIGNMENT_MISMATCH
exception CX_SY_IMPORT_MISMATCH_ERROR
ABAP program SAPLAQRUNT
Anwendungskomponente BC-SRV-QUE
Date and Time 05.06.2013 14:40:03

Has anyone gone through a similar situation, or know the solution.

Thank you.
