Can't create a new group

[netweblogic]

I upgraded to 1.1.1 and I can't create new groups. Error and my solution below:

Error logs say this:
[15-Oct-2009 02:57:25] WordPress database error: [Field 'avatar_thumb' doesn't have a default value]
INSERT INTO wp_bp_groups (

creator_id,
name,
slug,
description,
news,
status,
enable_wire,
enable_forum,
date_created

) VALUES (

173, 'Forum Testing', 'forum-testing', 'Test', 'test', '', 1, 1, FROM_UNIXTIME(1255546645)

)

My Solution:
Change the default values of avatar_thumb and avatar_full:

ALTER TABLE wp_bp_groups CHANGE date_created date_created DATETIME NOT NULL ,
CHANGE avatar_thumb avatar_thumb VARCHAR( 250 ) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL ,
CHANGE avatar_full avatar_full VARCHAR( 250 ) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL

Thought I should add, the solution had no issues with regards to assigning an abstract gravatar to the group during creating process. Also, uploading/deleting a new avatar was no problem either.
