This can happen. Check if there is column rdb$field_precision in table
rdb$fields. If no, you will need to build yourself a custom version of
JayBird where this field is not used.

Is there anything that prevents you from upgrading to Firebird? As far
as I know, IB 6.0 was never considered as stable, at least Firebird
1.0.2 has a lot of fixes after IB 6.0 was released.
