the URL generates Warning: mysql_data_seek(): Offset 0 is invalid for MySQL result index 125 (or the query data is unbuffered) in /usr/local/apache/common-local/php-1.5/includes/Database.php on line 612
From what I can tell, this error is being generated because the URL specifies the group to be listed as being "checkuser" - there is no such group, as far as I'm aware. Interestingly, the form used to select which group to be viewed also inserts this value, however, specifying another group, in e.g. http://eo.wikipedia.org/Special:Listusers&group=bots will work fine.
Fixed in CVS HEAD.
