[Plugin: Simple User Admin] Bug? Unpopulated blog list when searching/adding a blog to a user.

I am managing a user. When I search for a blog to add the user to, “Choose the blog to add this user to”, rather than display a list of blogs that match the search criteria, it displays “Choose user:” with a selection box populated only by “(,)”.

The inverse – adding a user to a blog – appears, at first test, to work fine.
