Make sure whatever you're binding to exactly the expected datatype. The data source to the control is a WIA.DeviceInfo object, the converter is just getting the name property for the dropdown text. I'm working with WIA, and there are several COM exceptions that appear in the VS output window, apparently related to the databinding for the ListView.
My only guess so far from searching is that there is some sort of default error template that is being applied to the control. The converter is not the source of the problem, I've tried binding directly to a property on the underlying object and the box still appears.The border disappears when I attempt to examine the control tree with Snoop.Other dropdown controls on the same page are not doing this.This is an XBAP application running in IE8.It will not go away once it appears, and it shows up over anything that I place on top of the control.
