I can’t create content types (poll_multiple) which have a pollfield. The following error is reported

user warning: BLOB/TEXT column 'field_quest_question' can't have a default value query: ALTER TABLE content_type_poll_multiple ADD `field_quest_question` TEXT DEFAULT '' '' in www\includes\database.mysql-common.inc on line 307.
user warning: BLOB/TEXT column 'field_quest_choice' can't have a default value query: ALTER TABLE content_type_poll_multiple ADD `field_quest_choice` TEXT DEFAULT '' '' in www\includes\database.mysql-common.inc on line 307.
user warning: BLOB/TEXT column 'field_quest_anonymous' can't have a default value query: ALTER TABLE content_type_poll_multiple ADD `field_quest_anonymous` TEXT DEFAULT '' '' in \www\includes\database.mysql-common.inc on line 307.
user warning: BLOB/TEXT column 'field_quest_poll_features' can't have a default value query: ALTER TABLE content_type_poll_multiple ADD `field_quest_poll_features` TEXT DEFAULT '' '' in www\includes\database.mysql-common.inc on line 307.

System: pollfield 6.x-1.13-beta1, cck-6.x-2.9, drupal 6.20, mysql 5.0.67, windows. The problem seems to be that mysql doesn't support DEFAULT values for BLOB and TEXT columns. Is it possible the default declaration to be removed from the module; See also http://drupal.org/node/143881.
