Permission denied to get property XULElement.selectedIndex

From Helpful

(..."when calling method: [nsIAutoCompletePopup::selectedIndex]")

This is an bug in firefox' autocomplete feature - in that this seems to happen when both the autocomplete and a user script access the same input field(verify).

The surest workaround is disabling it by adding an attribute to the input field.

It seems to have been around since 0.9.2 and still exist in 1.5; it seems slated to be solved in firefox 2.
