I just went to look for something on Special:ListUsers, and after a few clicks got an empty list when i tried to display all members of a certain group. Looking at it a little closer, i noticed that after entering a name and starting the search, and then blanking the input field and searching again, i got no results. The "username" parameter in the URIs query string is empty (http://en.wikipedia.org/w/index.php?title=Special%3AListUsers&username=&group=sysop&limit=50). Oddly, it seems to randomly be working and not working, changing randomly with every click on the OK button.
Also made a video of it, in case you don't believe me. :-P
Seems ok at present; may have been a temporary glitch due to the borked DB server that was in for a bit.
Yep. Getting this worked out; user_group fields need to be converted to varbinary before the 5.0 migration or the padding breaks.
Confirmed, works fine now.
