Using .NET 4.0 and AjaxControlToolkit 4.1.50508.0, <pages controlRenderingCompatibilityVersion="4.0" clientIDMode="AutoID" />, I see that AsyncFileUpload will always kick back "The file attached was invalid" when in the third index of a Repeater (only index 3 is affected, greater indexes work correctly).
I've attached a screenshot and a sample project showing the error in about as few lines as possible.
