Undefined property: views_handler_field_views_raw_sql::$field_info in last development release

After upgrade to the last development release, a new problem appeared:

Notice : Undefined property: views_handler_field_views_raw_sql::$field_info dans views_raw_sql_get_query_tokens() (ligne 109 dans /home/clients/e1cf8f7f73cd08534e89eb0f9bde45d2/web/modules/views_raw_sql/views_raw_sql.module).

Warning : Invalid argument supplied for foreach() dans views_raw_sql_get_query_tokens() (ligne 110 dans /home/clients/e1cf8f7f73cd08534e89eb0f9bde45d2/web/modules/views_raw_sql/views_raw_sql.module).

... repeated several times.

This is probably related to recent commit http://cgit.drupalcode.org/views_raw_sql/commit/?id=ee8bdc9.

Thanks for your investigations.
