Ok seems this was happening because a command was failing and retrying (and the command was already used or something). First failure was:

System.Data.OracleClient.OracleException was caught
  Message=ORA-01008: not all variables bound

  Source=System.Data.OracleClient
  ErrorCode=-2146232008
  Code=1008

  InnerException: 

This is happening because of incorrect null parameter handling in OracleDatabase.create_parameter. It should be:

private IParameter<IDbDataParameter> create_parameter(string name, DbType type, object value, int? size)
{
    IDbCommand command = server_connection.underlying_type().CreateCommand();
    var parameter = command.CreateParameter();
    command.Dispose();

    parameter.Direction = ParameterDirection.Input;
    parameter.ParameterName = name;
    parameter.DbType = type;
    parameter.Value = value ?? DBNull.Value; // <--- fixed
    if (size != null)
    {
        parameter.Size = size.Value;
    }

    return new AdoNetParameter(parameter);
}

This now works. However I found another bug in some SQL:

SELECT id
FROM (SELECT * FROM {0}_{1}
        WHERE 
            NVL(repository_path, '') = NVL(:repository_path, '') -- fixed
        ORDER BY entry_date DESC)
WHERE ROWNUM < 2

This happens because NULL == NULL does not evaluate to true in PL/SQL. If you do not have a repository path specified, this WHERE clause would always have evaluated to false and thus never returned any rows.

As well I found another bug in insert_version_and_get_version_id:

return Convert.ToInt64((decimal)run_sql_scalar(get_version_id_script(), ConnectionType.Default, select_parameters));

The (decimal) cast is not required here. In fact it actually causes errors - in my case the unneccessary cast was causing a NullReferenceException (because there were no rows in the Version table, run_sql_scalar returned null which cannot be casted to a value type).

I'm at work at the moment but will try to get a pull request to address these issues when I get home.
