[Koha] Software error: ~~Duplicate entry '320' for key 'PRIMARY' at~~~

Another error....is this one also related to the bug 18003 ? seems very similar.

From one of my staff...

________________________________________________ I put a book that is checked out on hold. When it is returned, the system tells me who is waiting. I confirm the hold When I check the book out to the patron, I get this message: Software error: DBIx::Class::Storage::DBI::_dbh_execute(): Duplicate entry '320' for key 'PRIMARY' at /usr/share/koha/lib/Koha/Object.pm line 121 ____________________________________________________ Any fix for this one ?? -S
