Recursion Error Down To One Subroutine

I've tracked a recursion error down to one subroutine, So when my form loads, it populates some listboxes from a database; any one of these causes the error:
ListboxQuery("select sculptname, sculptid from sculptures;", CloseSculptList, "sculptname", "sculptid")
ListboxQuery("select distinct eventtype from events;", EventTypeList, "eventtype", "eventtype")
'etc, etc

And here's the subroutine (it's querying a MySQL database):
Public Sub ListboxQuery(ByVal queryText As String, ByVal resultObject As Object, ByVal resultDisplay As String, ByVal resultValue As String)
'queries the database for a 1- or 2-column list of values to display in a listbox
Dim myCommand As New MySqlCommand
Dim myAdapter As New MySqlDataAdapter
[Code] .....

The error is the standard recursion error:
An error occurred creating the form. See Exception.InnerException for details. The error is: The form referred to itself during construction from a default instance, which led to infinite recursion. Within the Form's constructor refer to the form using 'Me.'

This is weird for two reasons: One, as you can see, the subroutine doesn't refer to the form at all, so I don't see how it could cause a recursion error, and two, I wrote this subroutine almost a year ago and it only caused this error last week.
