When you open these users profiles in the Control Panel, what groups does it display that they belong to?
What I find a little odd is the last line of your errors.

That could mean a corrupted script???? I would at least check the includes/config.inc.php file to see it is hosed.
If you look at the queries he supplied, the part of the code that checks if they have group images is returning an error because no group ids are being retrieved from the database for the query, which would generally indicate that these users do not belong to any user groups.

The code should display an array of group ids that the user belongs to (such as the users group, GM/Mod groups, and/or the Admin group), his is returning no group ids at all.
This could happen if one purged a default group (such as changing the default group users are added to) without reassigning the users to another group.
