Comment 14 for bug 1341562

I think I have spotted what makes this bug happen and what makes the icon work. If I enter my password promptly when the dialog comes up, the icon usually doesn't work. If I delay (e.g. fire up the computer, then go and do something else before coming back to enter my password) it invariably does.

I hope this narrows down the possibilities of what may be causing the bug, e.g. some process that is interrupted by the completion of the password dialog.
