webfm install error on mysql (InnoDB)

i got this error message when trying to install webfm !
I'm newbie with php so i dont know how to fix it, only thing is i report here and hope if someone can fix it. I think this happen only apper when you install webfm on mysql (that run InnoDB, Myisam is ok)

user warning: BLOB/TEXT column 'fdesc' can't have a default value query: CREATE TABLE drp_webfm_file ( `fid` INT unsigned NOT NULL auto_increment, `uid` INT unsigned NOT NULL DEFAULT 0, `fpath` MEDIUMTEXT NOT NULL, `fsize` INT unsigned NOT NULL DEFAULT 0, `fmime` VARCHAR(255) NOT NULL DEFAULT '', `ftitle` VARCHAR(255) NOT NULL DEFAULT '', `fdesc` TEXT NOT NULL DEFAULT '', `fcreatedate` INT NOT NULL DEFAULT 0, `flang` VARCHAR(255) NOT NULL DEFAULT '', `fpublisher` VARCHAR(255) NOT NULL DEFAULT '', `fformat` VARCHAR(255) NOT NULL DEFAULT '', `fversion` INT NOT NULL DEFAULT 0, `perm` TINYINT NOT NULL DEFAULT 0, `dl_cnt` INT NOT NULL DEFAULT 0, PRIMARY KEY (fid) ) /*!40100 DEFAULT CHARACTER SET UTF8 */ in D:\www\drupal-6.14\includes\database.inc on line 529.

my system is:
==========
server: windows nt
mysql 5.1.37 (INNODB) (MyISAM is ok)
Apache 2.2.13
PHP Version 5.2.10
drupal 6.14
